The character you know and love walks off set on one side, and a couple of seconds later walks in on the other side, only he's wearing different clothes! And talking funny! And everyone's calling him Cousin Rick, not Fred!
For many a reason both solid and sordid, an actor might find themselves playing more than one role on the same show. It might be a twin brother (or cousin, aunt, etc. — television has never been fussy on the details). A male character may be put in drag to play his own mother, who looks a lot like him. More than a few action shows have had a lookalike try to frame the main character. Whatever the reason, the actor is Acting for Two. Sometimes more, depending on the role.
It happens occasionally in other media as well, but when the same actor plays multiple characters on TV or in a film, it usually has a very specific purpose. In theatre, it's just as often an economic use of talent. Often certain role-pairings become traditional, so for example some film versions of Peter Pan still cast the same actor for Hook and Mr Darling - even though they could afford two actors, and the stage tradition only arose because of their lack of scenes together. Maybe because it seems symbolic of... something.
This tradition goes way way back. Classical Greek drama was usually performed by two or three actors (wearing masks) plus chorus. As a result, you never see more than three principal characters at the same time, in very specific combinations: Hecuba talks to Cassandra and a Greek Herald, then Cassandra goes offstage (and changes masks) and comes back on as Andromache, then Andromache and the Herald go offstage and come back as Helen and Menelaus... To this day "doubling" of roles is common in theatre, especially in No Budget productions.
See Double Vision for a look at how they manage the trick of getting an actor on-screen more than once, when needed.
Understandably this happens a lot in voice acting, because one person playing two characters can get pretty difficult in live-action if you want both characters in the same place at the same time during the show/film's run, whereas the only hurdle you have to overcome with voice acting is the two characters sounding too similar, and a good voice actor can work around that by differentiating their voice between roles. This is common in a lot of British children's TV shows from before the 2000s, since many of them were produced on a shoestring budget and couldn't afford a big cast, shows like The Clangers, The Wombles and the English dub of The Magic Roundabout being prominent examples. Not to be confused with Talking to Themself, in which the actor plays different personalities of a single character in-story. For the other kind of "acting for two", see Hide Your Pregnancy. Contrast Making Use of the Twin, where an actor happens to have a twin who's cast in order to avoid this trope.
In countries with a smaller voice acting industry, this tends to be quite widespread. Just check out the Indonesian dub's cast for Squid Game.
In audiobook narration, with a few exceptions such as Full Cast Audio a single person voices the whole cast and usually tries to differentiate all of the characters' voices, to varying effect. This is so universal that it's not worth listing all the examples.
- Alternate Self: When everybody has their counterpart, you can have twice as many characters per actor.
- Mirror Universe: Evil Alternate Self.
- And You Were There: Like a Mirror Universe, but with a fun-house mirror (think The Wizard of Oz).
- But You Were There, and You, and You: A character tells a story, and the characters are depicted as people the storyteller knows.

- Evil Twin: Particular case of this.
- Reincarnation: In the "looks just like the old me" variant.
- Significant Double Casting: When having the same actor play multiple characters has a metatextual meaning significant to the story.

- JoJo's Bizarre Adventure:
- Diamond is Unbreakable: In the Latin American Spanish dub, Irwin Daayán voices both Jotaro and Rohan.
- Golden Wind: During Chariot Requiem's "Freaky Friday" Flip, this happens to everyone. Rather than switch voice actors, they chose to keep voices the same.

- One Piece:
- For the anime, all of the ten voice actors for the Straw Hats acted for two — or in some cases for three or four — at various times. Akemi Okamura, Kappei Yamaguchi, Kazuya Nakai and Hiroaki Hirata did it frequently, as they voiced Nami, Usopp, Zoro and Sanji, respectively, in addition to minor/supporting characters and creatures (such as Okamura's Su and Gonbe, Hirata's Karoo, or Yamaguchi's Eyelash). Katsuhisa Hoki did this in the Marineford arc, before Moria began to appear less often. For the Time Skip, eight of the Straw Hat actors would go on to play the Fake Straw Hats.
- Tomomichi Nishimura also did it in episodes featuring Miyagi and Hyogoro.
- Ryūzaburō Ōtomo voiced Sir Crocodile, Kozuki Sukiyaki as well as Tenguyama Hitetsu. The latter two is an example of Significant Double Casting, as Kozuki Sukiyaki is Hitetsu.
- Hideyuki Hori voiced Bartholomew Kuma as well as Sanji's father Vinsmoke Judge.
- Toshiyuki Morikawa voices Enel and Hatchan.
- Kotono Mitsuishi voices Boa Hancock as well as S-Snake, which is significant as all the other Seraphims are voiced by different seiyuus other than the Warlords they are based upon.
- Yasunori Masutani voices Disco, Saint Jalmack and Saint Shepherd Ju Peter.
- Kazuhiro Yamaji voices Senor Pink as well as Figarland Garling.

- A handful of voice actors from the Funimation dub play multiple roles. For example, Brina Palencia voices Chopper, Zoro (as a child), Rongo and Carmen, Colleen Clinkenbeard plays Luffy, Myure (the Bellamy Pirates' doctor) and a Southbird, and Stephanie Young voices Nico Robin and her mother Olvia (this is a carry-over from the Japanese where Yuriko Yamaguchi also voiced Olvia).
- Sailor Moon:
- All of the first anime's principal performers acted for two — or in some cases for three or four — at various times. Chiyoko Kawashima did it for most of the series, as she was the voice of Shingo Tsukino and Haruna Sakurada, in addition to her Sailor Guardian role. Keiko Han did this most often in the first season, before Queen Beryl began to appear less often (likewise Rika Fukami and Keiichi Nanba). Kotono Mitsuishi also did it in Sailor Stars, as she's the voice of Usagi/Sailor Moon and Chibi Chibi.
- In the Polish dub of the Make Up! Sailor Senshi R special, Queen Beryl and Luna were voiced by Magdalena Krylik.
- The first English dub also had a limited batch of voice actors. As such, all of them could be heard voicing bit parts at different times in the series, when the secondary batch of actors were otherwise unavailable.
- This carries over into the second English dub as well. For example, Stephanie Sheh voices Usagi/Sailor Moon and Chibi Chibi, Lucien Dodge voices Zoisite and Motoki Furuhata, Tara Platt voices Ikuko Tsukino and Kaolinite, and so on.
- In the Albanian dub, Ledina Rabdishta voices both Naru and Setsuna.
- Yo-kai Watch: In the French dub, Fanny Bloc voices Jibanyan, Komasan, Komajiro, and Kyubi.

- Noonbory and the Super 7: In the English dub, both Mungury and Coldygury are voiced by Rod Beilfuss.
- Pororo the Little Penguin: In the Spanish dub, both Pororo and Harry are voiced by Miriam Aguilar.
- An in-universe example. On the album Arthur's Really Rockin' Music Mix, the final track, "Goldilocks and the Bears Trio as Told by Sue Ellen" is actually a play presented by Sue Ellen because she claims she can't sing. She tries to cast D.W. for the role of Goldilocks, but D.W. walks off, saying that the role isn't big enough for her talent. As such, Buster is forced to play the role of Goldilocks, even though he's already been cast as the Wolf. Hilarity Ensues.
Buster: (with a bad German accent) Hello. I am Wolfgang!Sue Ellen: (moans) Hold it! You're Goldilocks!Buster: Yeah, but I was the wolf first. Does this mean I have to chase myself?
- Barbie:
- Barbie as the Princess and the Pauper: Kelly Sheridan voices both Anneliese and Erika, although they had different singing voices. This also applies to the German dub (Ilona Brokowski) and the Spanish dub (Melanie Henríquez).

- Austin Powers: Mike Myers famously plays both the titular secret agent as well as his Arch-Enemy, the Blofeld Expy Dr. Evil. In the following movies he would also play Fat Bastard and Goldmember. In fact, "acting for two" seems to be a trademark of Myers, as he also plays both Charlie and his father Stuart in So I Married an Axe Murderer. In this movies' Spin-Off series, The Pentaverate, he plays no less than eight different roles.
- In the Fantômas film series, Jean Marais played both Fandor and Fantômas (though the latter, due to Evil Sounds Deep requirements, was voiced by Raymond Pellegrin). Marais also played a Kidnapped Scientist in the second film.
- The Fun, The Luck & The Tycoon: Chow Yun-fat plays both Lam Bo-Sang and Stinky.
- In Furiosa: A Mad Max Saga, Lachy Hulme played both Immortan Joe and Rizzdale Pell (Dementus's one-eyed Number Two) and Elsa Pataky played bith the Vulvalini General and Mr. Norton (a disfigured member of Dementus's gang).
- The page image is from Nutty Professor II: The Klumps. In The Nutty Professor (1996), the film's Signature Scene isn't related to its sci-fi plot, but when Sherman has dinner with his family and the entire family except his young nephew is played by Eddie Murphy hamming it up as different characters. The sequel gives the family a larger role in the story.
- Om Shanti Om: Deepika Padukone plays Shantipriya and Sandy.
- Paradise Hills: Emma Roberts played Uma, along with her substitute, Anna.
- In Upgrade, Logan Marshall-Green plays both Grey Trace, and Stem after taking over his body.
- In Les Visiteurs Film Series, several characters' descendants/ancestors are played by the same actors and actresses (the Identical Grandson entry gives more details), such as Christian Clavier (most prominently Jacquouille and his descendant Jacquart), Valérie Lemercier (Lady Frénégonde and her descendant Béatrice de Montmirail in the first film) and Muriel Robin (The Other Darrin for the latter roles in the first sequel). Clavier really takes the cake, as he acts for four in The Corridors of Time (adding a manure-gathering brother to Jacquouille in The Middle Ages and a Revolutionary prosecutor), not to mention one more descendant of Jacquouille in Bastille Day.
- Zack Snyder's Justice League, Ray Porter played both Darkseid and an ancient human blacksmith.

- In the first TRON, the human characters and their programs were played by the same actors. Jeff Bridges played both Kevin Flynn and CLU, Bruce Boxleitner played Alan Bradley and Tron, Cindy Morgan played Lora Baines and Yori, Barnard Hughes played Walter Gibbs and Dumont, and David Warner pulled a triple by playing Ed Dillinger and Commander Sark while also providing the Master Control Program's voice.

For example, the circus boss Captain Billy is also the ringmaster, his enforcer Otto is Primo the World's Strongest Bear, and their head clown is the janitor (which turns into a plot point late in the book).
- The Golden Hamster Saga: Freddy's Final Quest has an in-universe example. The characters go to see a stage production of Freddy in Peril, with the same two actors playing both Enrico and Caruso and Fleischkopf and Brewster.

- "Sgt. Wilson's Little Secret" has a scene where Walker bothers Wilson while he is waiting for Mrs. Pike outside of her home, and once Walker leaves and Mrs. Pike comes out, an off-screen ARP warden yells, "Oi, put that light out!". As the warden is off-camera, James Beck voices him in addition to playing Walker.

- During pre-production, Jack Haig was asked to play both Jones and his twin brother, George. This twin was dropped early in production.
- Fraggle Rock:
- All of the five principal Fraggle performers acted for two - or in some cases, for three or four - at various times. Steve Whitmire and Dave Goelz in fact did it in almost every episode, as they were the performers of Sprocket and Traveling Matt, respectively, in addition to their Fraggle Five roles, plus the additional minor/supporting characters they performed (such as Whitmire's Marlon Fraggle and Murray the Minstrel, or Goelz's Philo, World's Oldest Fraggle and Large Marvin). Jerry Nelson did this most often in season one, before the Trash Heap and Pa Gorg began to appear less often (likewise Richard Hunt), but still did it regularly throughout the series run. Kathryn Mullen and Karen Prell had relatively fewer episodes in which they played multiple roles, but they did do it on occasion - for instance, in episodes featuring both Mokey and Cotterpin, or Red and Fluffinella.
- This carries over into the 2022 reboot as well. For example, John Tartaglia now performs Gobo, Sprocket, Architect Doozer, and Gunge; Dave Goelz still voices Boober, Traveling Matt and World's Oldest Fraggle although the puppetry is now handled by others (two more of Goelz's characters, Philo and Large Marvin Fraggle, are recast to Dan Garza and Frank Meschkuleit, respectively); and so on. Karen Prell (still performing as Red) actually adds a few new characters as well, notably Icy Joe.
- A handful of voice actors in the 2021 Japanese redub handle multiple roles. For example, Riki Kitazawa dubs both of Dave Goelz's major characters (Boober and Uncle Matt), and Cantus and Convincing John (both Jim Henson characters) were dubbed by Youhei Tadano.
- In the Inside George Webley episode, "A Lean and Hungry Look", Jack Woolgar plays the misery of a pub landlord who kickstarts George's desire to lose weight, and also briefly plays the bemused gent who George and Simon run past during their workout.
- The Last of the Baskets: In "It's a Living", Arthur Lowe plays both Mr. Bodkin and his brother, the Reverend Theobold Bodkin.
- M*A*S*H: In the episode "Mail Call, Again" Gary Burghoff portrays his character Radar's mother in the home movie sent from Iowa.
- Mystery Science Theater 3000 did this often, as they had a limited cast. For the first seven seasons, Trace Beaulieu played both Mad Scientist Dr. Forrester and Crow, one of the robots on the Satellite of Love. In later seasons, Kevin Murphy played both Tom Servo and Bobo, while Bill Corbett played Crow and Observer. And that's just the regular cast; actors would frequently play one-off characters in sketches as well.
- On the Buses: In "Going Steady", Blakey shows Stan a picture of his twin sister, also played by Stephen Lewis.
- The Onedin Line: Alongside Captain James Onedin, Peter Gilmore also played Cousin Richard in "The Passenger".
- Porridge:
- Ronnie Barker played Fletcher and also voiced the judge in the intro.

- Red Dwarf:
- "Dimension Jump" has Chris Barrie playing dual roles as Arnold Rimmer and Ace Rimmer, his parallel universe counterpart, in the character's first appearance. The episode also has Craig Charles playing his own counterpart Spanners, as well as Danny John-Jules, Hattie Hayridge and Robert Llewellyn as Padre, Mellie and Bongo respectively (Llewellyn being unrecognisable without Kryten's prosthetics).
- Llewellyn has played some extra roles in a handful of other episodes, both with the prosthetics (Kryten's hallucinatory alter-ego Jake Bullet in "Back to Reality") and without (Jim Reaper in "The Last Day").
- On Time Bandits (2024), James Dryden and Felicity Ward play both Mr. Mike Haddock and Mrs. Lisa Haddock as well as those characters own parents: Grandpa Haddock and Lisa's mother (surname unknown).
- The Toy Castle: Rick Jones, in addition to narrating, voices all of the characters.
- Dungeons & Daddies: In tabletop roleplaying games, the game master plays the vast majority of the non-player-characters. This results in Dungeon Master Anthony Burch (and later Will Campos) sometimes having to have full conversations with himself when two non-player-characters interact. Typically, this is played for laughs with the players cutting in and making comments, but sometimes (like when Grant reveals his depression and confesses his feelings to Yeet after the Supper Bowl) the scenes are played completely straight.
- King Kirby has at least four actors, three of whom voice multiple characters, while only one plays Kirby himself. It is incredibly easy to tell which actor is playing each role.
- The Magnus Archives: Due to difficulty casting someone new on a short notice, the voice actor for Martin Blackwood (Alex Newall) was additionally cast as Jared Hopworth (though it's hard to tell they're played by the same person due to the filters layered over Jared's voice). The two characters briefly interact in season 5.

- Janet Brown plays Janet Brown and Vera Timkins.
- Close attention to the closing credits reveals that the main cast appears as some of the caricature-voiced minor characters.
- The Stan Freberg Show: More than one instance, due to the limited cast and Freberg's talent for voices. In the interview with the Abominable Snowman, Freberg does the Snowman voice by inhaling as he speaks, making his rapid-fire back-and-forth dialogue even more impressive.
- Carry On Escaping: Kommandant Fokker and Lieutenant Briggs were intended to be played by the same actor.
- As You Like It: In many productions, the good Duke Senior and his evil usurping brother Duke Frederick (who never appear on stage together) are played by the same actor, making Frederick an Evil Twin.
- Cross Road:
- Costa the violin teacher in act 1 and Hector Berlioz in act 2 are played by the same actor (Kenji Sakamoto in the 2024 production). Costa is Niccolo Paganini's music teacher in his youth, who celebrates his talent at first, then denounces him for having acquired musical skill from a Deal with the Devil. Berlioz is another great composer of the era, younger than Paganini, who has fallen on hard times. At first, Paganini rejects him, but eventually he helps him. Costa is a minor figure, but in act 1, he has power over Paganini; Berlioz, on the other hand, is important, but this time, Paganini is the one with power over him.
- In the Japan Musical Festival Winter 2022 concert, Akinori Nakagawa, who played the devil Amduscias in the original cast, performed both roles (Amduscias and Niccolo) in the duet "Contract of Blood", singing Amduscias live with a pre-recorded projection of himself as Niccolo.
- Fireman Sam On Stage: Andy Medhurst acts as both Elvis and Tom, while Adele Scott plays both Penny and Dilys.
- In A Gentleman's Guide to Love and Murder, all eight of the D'Ysquith heirs plus Chauncey D'Ysquith, both male and female, are portrayed by a single actor; in the original cast, Jefferson Mays earned a Tony nomination for the feat.
- In Little Shop of Horrors, the actor who plays Orin Scrivello usually plays several other roles, such as a bum during "Skid Row (Downtown)", the first customer to notice the Audrey II, the radio host who interviews Seymour, all three business people during "The Meek Shall Inherit", and Patrick Martin.
- A Midsummer Night's Dream: The mortal rulers Theseus and Hippolyta, and the fairy rulers Oberon and Titania, are often played by the same duo of actors.
- In Peter Pan (1904), the same actor traditionally plays Mr. Darling and Captain Hook. J. M. Barrie, the author, reportedly suggested that Captain Hook should be played by the same actor as Mrs. Darling.
- Team StarKid productions do this to keep the cast small. Most of the cast will play multiple small roles in addition to their main characters and/or switch costumes to join the ensemble when their main character is offstage.
- Joey Richter plays "Everyone Else" in The Trail to Oregon!, meaning almost every character outside the main family. Every other cast member has an extra role or two when needed.

Since the player character is a Heroic Mime, it was easy for Bosch to voice Adachi with his normal voice without the fact that he was voicing them both being too obvious. After the game was adapted to anime and spin-offs like Persona 4 Arena Ultimax and Dancing All Night, giving the player character (now named Yu Narukami) actual dialogue, Bosch began to differentiate them with Yu speaking in his normal voice, and Adachi's voice being higher-pitched and raspier.
