15 TV Actors Who Played More Than One Character

Playing one memorable character on a television show is challenging enough. Playing two, three, or even a dozen? That's an entirely different level of talent. Over the years, some of television's most recognizable actors have taken on multiple roles within the same series, sometimes portraying identical twins, mysterious doppelgangers, or characters who have absolutely nothing in common.

In some cases, the transformations were so convincing that viewers didn't even realize they were watching the same performer. Other times, the resemblance was a major part of the storyline, allowing actors to showcase their range in ways that a single character never could. From classic sitcoms and supernatural dramas to modern science-fiction favorites, these 15 actors proved that sometimes one role just isn't enough.

Show: Atlanta
Roles: Earnest "Earn" Marks, Teddy Perkins, Kirkwood "Mr. Chocolate" Chocolate

Donald Glover didn't just create and star in FX's critically acclaimed series "Atlanta." He also used the show as an opportunity to disappear into some truly unexpected characters. His primary role was Earnest "Earn" Marks, a struggling manager trying to build a music career for his cousin, rapper Alfred "Paper Boi" Miles. However, Glover occasionally stepped away from Earn to play characters who looked and behaved nothing like him.

One of the most memorable was Teddy Perkins, the unsettling, reclusive musician introduced in a second-season episode bearing his name. Extensive makeup and prosthetics made Glover nearly unrecognizable. He pulled off another transformation in the fourth-season episode "Work Ethic!," portraying Kirkwood Chocolate, an eccentric entertainment mogul known as Mr. Chocolate. Both characters demonstrated Glover's ability to blend comedy, discomfort, and social commentary into performances that left a lasting impression.

Show: Living with Yourself
Roles: Miles Elliot and his clone

What would happen if you discovered that someone had created a better version of you? That's the uncomfortable question at the center of Netflix's 2019 comedy-drama "Living with Yourself," starring Paul Rudd. He plays Miles Elliot, a frustrated advertising executive whose personal and professional life has become increasingly disappointing. Hoping to turn things around, Miles undergoes an unusual treatment at a mysterious wellness facility.

Unfortunately, the procedure doesn't work quite the way he expects. Instead, it produces a clone who is more confident, energetic, and seemingly better equipped to handle Miles' life. Rudd plays both versions, often appearing opposite himself as the original Miles struggles with jealousy, insecurity, and the unsettling realization that his replacement might actually be happier. Although the two characters share the same identity and appearance, Rudd gives them distinctly different personalities, making the unusual premise surprisingly believable.

Show: The Good Place
Roles: Good Janet, Bad Janet, Neutral Janet, Disco Janet, and more

D'Arcy Carden turned what initially appeared to be a fairly straightforward supporting role into one of the most impressive recurring performances on NBC's "The Good Place." Her character, Janet, is an all-knowing, humanlike entity who assists the inhabitants of the afterlife. The original Good Janet is endlessly cheerful, helpful, and almost impossibly patient. However, viewers eventually discover that different regions of the afterlife have their own versions of Janet, all played by Carden.

There's the rude and sarcastic Bad Janet, the emotionally flat Neutral Janet, and the wonderfully bizarre Disco Janet. Carden's biggest acting challenge came in the acclaimed third-season episode "Janet(s)," when several human characters temporarily assumed Janet's appearance. That meant Carden had to portray Eleanor, Chidi, Tahani, and Jason while retaining their individual mannerisms and personalities. It was a remarkable demonstration of her comedic timing and versatility, and one of the show's most memorable creative achievements.

Show: The Vampire Diaries
Roles: Elena Gilbert, Katherine Pierce, Amara

Nina Dobrev had her hands full throughout her time on The CW's supernatural drama "The Vampire Diaries." She began the series as Elena Gilbert, an ordinary teenager whose life becomes entangled with two vampire brothers, Stefan and Damon Salvatore. However, the show's complicated mythology eventually reveals that Elena is part of a centuries-spanning line of supernatural doppelgangers.

That revelation allowed Dobrev to take on the role of Katherine Pierce, a manipulative vampire whose resemblance to Elena creates endless problems for the show's central characters. Katherine is cunning, ruthless, and frequently several steps ahead of everyone around her, making her a sharp contrast to the compassionate Elena. Dobrev also portrays Amara, an ancient immortal whose appearance connects the doppelganger storyline to the series' larger mythology. Switching between these characters often required Dobrev to give dramatically different performances while looking almost exactly the same.

Show: Family Matters
Roles: Steve Urkel, Stefan Urquelle

Few television characters are more closely associated with the 1990s than Steve Urkel. With his oversized glasses, suspenders, high-pitched voice, and unforgettable catchphrases, Jaleel White transformed the nerdy neighbor on "Family Matters" into one of the decade's biggest sitcom personalities. But White eventually received an opportunity to show audiences an entirely different side of his acting abilities.

During the show's fifth season, Steve develops a scientific formula designed to transform himself into someone more appealing to his longtime crush, Laura Winslow. The result is Stefan Urquelle, a smooth-talking, fashionable, and remarkably confident version of Steve who couldn't be further removed from the original character. Stefan first appears in the episode "Dr. Urkel and Mr. Cool" and eventually becomes a recurring part of the series. White's ability to alternate between the awkward Steve and the effortlessly charming Stefan helped demonstrate that there was much more to his talent than one iconic sitcom character.

Show: Orphan Black
Roles: Sarah Manning, Alison Hendrix, Cosima Niehaus, Helena, Rachel Duncan, and numerous other clones

If there's one actress who deserves special recognition for playing multiple characters in a single television series, it's Tatiana Maslany. Throughout the five-season science-fiction thriller "Orphan Black," Maslany portrayed an extraordinary collection of genetically identical women who couldn't have been more different from one another. The story begins with Sarah Manning, a troubled young woman who discovers that she is one of several clones created through a secret scientific program.

As the mystery unfolds, viewers meet the tightly wound suburban mother Alison, the brilliant scientist Cosima, the unpredictable Helena, and the calculating corporate executive Rachel, among many others. Maslany gave each character a recognizable voice, posture, personality, and set of mannerisms, making it surprisingly easy to forget that the same actress was playing all of them. Her remarkable performance earned her the 2016 Primetime Emmy Award for Outstanding Lead Actress in a Drama Series, a well-deserved recognition of one of television's most ambitious acting achievements.

Show: Heroes
Roles: Niki Sanders, Jessica, Tracy Strauss

Ali Larter was among the original stars of NBC's superhero drama "Heroes," playing Niki Sanders, a mother struggling to protect her family while dealing with extraordinary abilities and a complicated psychological condition. Niki possesses superhuman strength and experiences a dangerous alternate personality named Jessica, whose aggressive behavior frequently creates problems that Niki cannot control.

After Niki's storyline concluded during the second season, Larter returned to the series in an entirely different role. This time, she played Tracy Strauss, a politically connected woman with the ability to freeze objects and people. The series eventually reveals that Niki and Tracy are two of three genetically identical sisters, with Barbara Zimmerman completing the trio. The twist gave Larter an opportunity to reinvent her presence on the show while expanding its increasingly complicated mythology. Rather than simply reviving Niki, the writers introduced a distinct character with her own personality, history, and supernatural powers.

Show: Agents of S.H.I.E.L.D.
Roles: Eric Koenig, Billy Koenig, Sam Koenig, Thurston Koenig, Ernest Koenig

Patton Oswalt brought plenty of humor to Marvel's "Agents of S.H.I.E.L.D.," but his involvement with the series became considerably more complicated than a single recurring guest appearance. He first appeared during the show's first season as Eric Koenig, a trusted S.H.I.E.L.D. agent working at a secret facility. Following Eric's death, viewers were introduced to his remarkably similar-looking brothers, beginning with Billy and later Sam and Thurston.

Each brother had a slightly different personality, allowing Oswalt to put his comedic talents to work while the series played with the mystery surrounding the Koenig family. His involvement came full circle during the show's seventh and final season, when the agents traveled back to 1931 and encountered Ernest "Hazard" Koenig, an ancestor of the familiar brothers. Playing five members of the same fictional family across different periods made Oswalt one of the show's most entertaining recurring performers.

Show: Outlander
Roles: Frank Randall, Captain Jonathan "Black Jack" Randall

Starz's historical fantasy drama "Outlander" gave Tobias Menzies the unusual challenge of portraying two men connected by family history but separated by centuries. In the 20th-century storyline, Menzies plays Frank Randall, the husband of Claire Fraser, whose mysterious disappearance throws their marriage into turmoil. Frank is an intelligent historian whose search for answers becomes increasingly complicated as the story unfolds.

When Claire travels back to 18th-century Scotland, she encounters Frank's ancestor, Captain Jonathan "Black Jack" Randall, a British Army officer with a sadistic and terrifying personality. Although the men look nearly identical, their behavior could hardly be more different. Frank is generally thoughtful and restrained, while Black Jack is cruel, manipulative, and frequently violent. Menzies' ability to portray both characters convincingly added another layer of tension to a series already filled with complicated relationships, shifting loyalties, and unexpected consequences of time travel.

Show: Law & Order
Roles: Defense Attorney Frank Lehrman, Detective Lennie Briscoe

For millions of television viewers, Jerry Orbach will always be Detective Lennie Briscoe, the sharp-witted New York City investigator who became one of the most beloved characters on NBC's "Law & Order." What some fans may not realize, however, is that Orbach actually appeared on the series before joining the main cast, and his original character was on the opposite side of the courtroom.

During the show's second season, Orbach guest-starred as defense attorney Frank Lehrman in the episode "The Wages of Love." The performance evidently made an impression, because he returned the following season as Detective Briscoe, a role he would continue playing for more than a decade. Briscoe's dry humor, streetwise attitude, and complicated personal history helped make him a defining figure in the franchise. Orbach remained a central part of the series until leaving the regular cast in 2004, shortly before his death later that year.

Show: Friends
Roles: Phoebe Buffay, Ursula Buffay

Lisa Kudrow's portrayal of Phoebe Buffay helped make "Friends" one of the defining sitcoms of the 1990s. Phoebe's unusual worldview, offbeat sense of humor, and surprisingly complicated past made her one of the show's most memorable characters. However, Kudrow also had the opportunity to play Phoebe's identical twin sister, Ursula, a far less considerate character whose appearances frequently caused trouble.

Interestingly, Ursula actually existed before "Friends" premiered. Kudrow originally portrayed her as a forgetful waitress on NBC's "Mad About You," beginning in 1993. When "Friends" debuted the following year, the writers incorporated Ursula into the new show's universe as Phoebe's twin sister. The connection created a memorable crossover between the two popular sitcoms while giving Kudrow a chance to portray contrasting personalities. Although the sisters looked identical, Phoebe was generally more caring and emotionally aware, while Ursula was often selfish, unreliable, and perfectly comfortable frustrating everyone around her.

Show: Deadwood
Roles: Jack McCall, Francis Wolcott

HBO's acclaimed Western drama "Deadwood" featured an enormous collection of unforgettable characters, but Garret Dillahunt managed to stand out by portraying two very different men during the show's original three-season run. His first role was Jack McCall, the troubled gambler responsible for shooting legendary gunslinger Wild Bill Hickok during the first season. McCall's erratic behavior and eventual downfall made him an important part of the show's early storylines.

Rather than leaving Dillahunt behind after McCall's story ended, the producers brought him back for the second season as Francis Wolcott, an educated but deeply disturbed agent working on behalf of powerful mining businessman George Hearst. Unlike the impulsive McCall, Wolcott presents himself as a polished professional, although his disturbing behavior eventually exposes a much darker personality. The two characters are unrelated within the story, making Dillahunt's return an especially unusual casting decision. His ability to make both roles believable helped turn the unconventional choice into one of the show's memorable performances.

Show: Doctor Who
Roles: Caecilius, the Twelfth Doctor

Long before Peter Capaldi became one of the most recognizable faces of "Doctor Who," he appeared in the long-running British science-fiction series as an entirely different character. During the 2008 episode "The Fires of Pompeii," Capaldi portrayed Caecilius, a Roman merchant living in Pompeii shortly before the catastrophic eruption of Mount Vesuvius. At the time, David Tennant was playing the Tenth Doctor, making Capaldi's appearance seem like a relatively ordinary guest role.

That changed in 2013, when Capaldi was cast as the Twelfth Doctor, officially taking over the lead role after Matt Smith's departure. The actor went on to play the Doctor through 2017, bringing a more intense, sometimes gruff personality to the iconic Time Lord. The series even acknowledged the resemblance between the Doctor and Caecilius, incorporating the familiar face into its mythology. What began as a supporting appearance ultimately became a fascinating connection between two different eras of one of television's longest-running science-fiction franchises.

Show: Twin Peaks
Roles: Laura Palmer, Madeleine "Maddy" Ferguson

Few television mysteries have captured audiences quite like the question at the center of David Lynch and Mark Frost's "Twin Peaks": Who killed Laura Palmer? Sheryl Lee portrayed Laura, the seemingly picture-perfect high school student whose murder exposes the unsettling secrets lurking beneath the surface of a small Washington town. Although Laura is already dead when the series begins, Lee's appearances in photographs, recordings, dreams, and flashbacks make the character an essential part of the story.

Lee eventually returned in a much more substantial on-screen role as Madeleine "Maddy" Ferguson, Laura's nearly identical cousin. Unlike Laura, Maddy has dark hair and a more reserved personality, but her resemblance to the murdered teenager creates an uneasy atmosphere among the people who knew her. Maddy becomes involved with the Palmer family as the investigation continues, adding another layer of mystery to the series. The second character was reportedly created after Lynch became impressed with Lee's performance and wanted to give her a larger role in the show.

Show: I Know This Much Is True
Roles: Dominick Birdsey, Thomas Birdsey

Mark Ruffalo delivered one of the most emotionally demanding dual performances on this list in HBO's 2020 limited series "I Know This Much Is True." Based on Wally Lamb's bestselling novel, the six-episode drama follows identical twin brothers Dominick and Thomas Birdsey, whose lives have been shaped by family trauma, complicated relationships, and mental illness. Ruffalo portrays both men, giving each a distinct physical and emotional presence.

Dominick is an increasingly exhausted man attempting to care for his brother while struggling with his own painful past. Thomas lives with schizophrenia and faces serious challenges that place enormous strain on their relationship. Rather than relying solely on visual effects or physical differences, Ruffalo conveys the brothers' individual experiences through their voices, expressions, and behavior. His performance earned him the 2020 Primetime Emmy Award for Outstanding Lead Actor in a Limited Series or Movie, providing a fitting recognition of the tremendous work required to bring both characters to life.
