32 Actors Who Heavily Altered Their Voice For A Role

Some of the most extraordinary performances in movie or TV history have seen the actor completely disappear into a role, not only changing their appearance but also adopting a voice almost entirely different from their own. Take a look at some of the most impressive voice alterations that an actor took on to perfect their unique portrayal of a now iconic character (or characters).

Robert De Niro (Cape Fear)

One thing that makes the 1991 remake of Cape Fear one of the most amusing Martin Scorsese/Robert De Niro collaborations is the actor's approach to playing Max Cady. The Academy Award-winning Italian-American dons a thick, over-the-top Southern accent but is still no less chilling as the sadistic, recently released convict seeking revenge on the defense attorney (Nick Nolte) who put him away.

Lupita Nyong'o (Us)

One of the scariest modern horror movie villains is Red (Lupita Nyong'o) from writer and director Jordan Peele's 2019 sophomore feature, Us. The Academy Award winner brilliantly differentiates the vengeful, "tethered" person from her above-ground double, Adelaide, and gives her an even more unsettling presence, with a raspy voice inspired by a condition called spasmodic dysphonia, which inhibits airflow and is commonly a symptom of traumatic experiences.

Daniel Day-Lewis (Lincoln)

As he would with any other role, Daniel Day-Lewis went to great lengths to become the sixteenth President of the United States for his Oscar-winning performance in Steven Spielberg's 2012 biopic, Lincoln. He even made sure to match Honest Abe's voice, which was high-pitched and reedy (according to the Library of Congress), as opposed to the low bellow many previous portrayals mistakenly attempted.

Mel Blanc (Looney Tunes)

To this day, it is almost shocking to learn that most of the original Looney Tunes characters were brought to life by just one actor. Until he passed away in 1989, Mel Blanc provided the diverse voices of Bugs Bunny, Daffy Duck, Elmer Fudd, and plenty more favorites under the Warner Bros. animation umbrella.

Austin Butler (Elvis)

The key to portraying Elvis Presley is nailing his distinct Southern drawl, which Austin Butler went to great lengths to perfect when he was cast as the influential musician in Baz Luhrmann's 2022 biopic. The work he put into the voice seemed to have a lasting effect on the actor, whom audiences could not help but notice continued to speak in the same accent during public appearances.

Seth MacFarlane (Various)

In addition to being one of the creative forces behind two of TV's longest-running hit animated shows for grown-ups, Seth MacFarlane is also responsible for bringing many of their most important characters to life. He voices Peter, Stewie, and Quagmire on Family Guy and plays Stan and Roger on American Dad – all of whom require him to be completely unrecognizable, while Family Guy's Brian is no different from his real voice.

Catherine O’Hara (Schitt's Creek)

What makes Moira Rose (Catherine O'Hara) one of the funniest characters on Schitt's Creek is the way she pronounces certain words with her over-the-top, posh accent. Classic examples include "baby" (beh-beh) and "enchiladas" (ahn-chuh-lah-dahs).

Jim Carrey (How The Grinch Stole Christmas)

It is still sometimes hard to believe that it is Jim Carrey playing the title role in Ron Howard's live-action adaptation of Dr. Seuss' How the Grinch Stole Christmas from 2000. Not only is he covered head-to-toe with green skin and matching fur in the Christmas movie classic but the comedic mastermind disguises his voice with an accent that earned comparisons to Sean Connery, as he told Entertainment Weekly.

Eddie Murphy (Coming To America)

Eddie Murphy started a career staple of playing multiple roles in the same movie with 1988's Coming to America. He dons an African accent to play Prince Akeem and brings his voice to higher octaves as Randy Watson and Clarence, but he undergoes the most intensive alteration of both his appearance and voice when playing elderly barber shop patron, Saul.

Heath Ledger (The Dark Knight)

The Dark Knight is a superhero movie that won Oscars for Sound Editing and for Heath Ledger's astonishing, transformative performance as The Joker. No matter how many times you watch Christopher Nolan's acclaimed 2008 sequel to Batman Begins, it is always shocking to hear that wheezy, menacing voice coming from the late Australian actor.

Dan Castellaneta (The Simpsons)

If you have ever seen any of comedian Dan Castellaneta's live-action acting credits, it might shock you to learn that his most famous role is Homer Simpson. However, the Simpsons cast member provides the voice of plenty more characters than the infantile, Duff-swilling family man, including Grampa Simpson, Krusty the Clown, and Groundskeeper Willie.

Bill Skarsgård (Nosferatu)

Bill Skarsgård is no stranger to dramatically altering his appearance and his voice for the sake of scaring the living daylights out of audiences, having played Pennywise in back-to-back creepy clown movies, It and It Chapter Two. However, his transformation into Count Orlok for Robert Eggers' 2024 reimagining of Nosferatu was an even more challenging process, requiring a month-and-a-half of vocal training to perfect the vampire's dread-inducing growl.

Joaquin Phoenix (Walk The Line)

Joaquin Phoenix did all of his own singing when portraying Johnny Cash in James Mangold's acclaimed music biopic, 2005's Walk the Line. While appearing on Late Night with Conan O'Brien that year, the future Oscar winner told the late night talk show host that he worked with a dialect coach to replicate the Man in Black's deep baritone voice as authentically as possible.

Amanda Seyfried (The Dropout)

For her Emmy-winning performance on the Hulu original true crime miniseries, The Dropout, Amanda Seyfried had the challenge of imitating the infamous low voice of Elizabeth Holmes, the founder and CEO of the fraudulent blood-testing company Theranos.

Hugh Jackman (X-Men)

Many have been shocked to learn that Hugh Jackman is an Australian as his most famous role is the Canadian-native, Adamantium-clawed mutant, Wolverine. Of course, the Tony winner does more than just drop his natural accent for the X-Men movies but also incorporates a deep, nigh-animalistic growl.

Stephanie Beatriz (Brooklyn Nine-Nine)

When Stephanie Beatriz debuted in the Brooklyn Nine-Nine cast, she used her natural, higher-tone voice to play Det. Rosa Diaz. However, over time, the character's voice became progressively deeper until the actor settled on a low, more gruff tone that better suited the cop's hard-edged exterior.

Christian Bale (The Dark Knight Trilogy)

To play the lead in Christopher Nolan's beloved live-action Batman movies, Christian Bale pulled double-duty on changing his voice. In addition to dropping his Welsh accent when appearing as Bruce Wayne, he adopted a gravelly, identity-concealing growl when patrolling Gotham as the Dark Knight.

Kristen Stewart (Spencer)

Kristen Stewart did more to earn her Academy Award nomination for portraying Princess Diana in the 2021 biopic, Spencer, than donning a blonde hairdo and an English accent. The actor revealed to Howard Stern that she went so far as to dramatically evolve her vocal inflection by opening her mouth more widely than she normally would and, as a result, practically altered her physical appearance in the film.

Phil LaMarr (The Adventures Of Jimmy Neutron: Boy Genius)

Prolific voice actor Phil LaMarr, in addition to his transformative characters as a MADtv cast member, has made himself unrecognizable for countless iconic animated roles, such as John "Green Lantern" Stewart on Justice League or the title hero of Samurai Jack. However, no blip on his resume is nearly as surprising as the recurring role of foreign exchange student Bolbi Stroganofsky on Nickelodeon's The Adventures of Jimmy Neutron: Boy Genius.

Mark Hamill (Batman: The Animated Series)

There are two different kinds of Mark Hamill fans. There are those who know the actor as Luke Skywalker from the Star Wars movies and then there are those who know him as The Joker on Batman: The Animated Series and many subsequent animated Batman movies. The voice he puts on for the role – a wonderful mix of comically over-the-top theatrics and scintillating intimidation – has been recognized as the definitive portrayal of the Clown Prince of Crime in the eyes of many DC fans.

Robin Williams (Popeye)

Robin Williams proved that he was the perfect choice to lead director Robert Altman's live-action adaptation of the Popeye comic strip. He matched the brave, spinach-swilling sailor's fast-paced growl, as originated by voice actor Billy Costello, to a tee in the 1980 film.

Maggie Wheeler (Friends)

Maggie Wheeler stole the show from the Friends cast with her recurring role as Janice Hosenstein, who was famous for her signature catchphrase, "Oh. My. GAWWWWWD!" What sold the character was her thick, nasally Brooklyn accent, which the actor came up with when she auditioned to play the character, as she revealed to Access Hollywood.

Idris Elba (Mandela: Long Walk To Freedom)

Idris Elba earned rave reviews for his portrayal of Nelson Mandela in the Oscar-nominated 2013 biopic, Mandela: Long Walk to Freedom. Being raised by West African immigrants helped the English-born actor develop an appropriate dialect to play the influential South African President, as he revealed to Oprah Winfrey.

Mia Goth (X)

Mia Goth played dual roles in Ti West's acclaimed A24 horror movie, 2022's X – both of which required her to conceal her mousy English accent. She spoke with a raspy Southern drawl as young aspiring starlet Maxine Minx and sounded similar, but significantly aged up, when playing homicidal elder, Pearl.

Megan Mullally (Will & Grace)

Megan Mullally absolutely earned her two Emmy Award wins for her committed performance as Karen Walker on the classic TV sitcom, Will & Grace. The key to the spoiled socialite's scene-stealing presence was her ear-piercing voice, which truly sounds nothing like the actor in real life.

Ana De Armas (Blonde)

Cuban-born actor Ana de Armas is known for having a strong accent, which she concealed in order to portray Marilyn Monroe in Blonde. Her commitment to matching the Hollywood icon's dialect in the 2022 Netflix original biopic would earn her an Academy Award nomination for Best Actress in a Leading Role.

Billy West (Various)

Billy West could be called the Mel Blanc of his generation as he can claim to have played about as many memorable animated characters as the iconic voice actor behind much of the Looney Tunes line-up did. To list just a few of West's best-known credits, he was both of the title characters from The Ren & Stimpy Show, took over as Popeye at one time, led Futurama as Fry, and plenty more.

Nicole Kidman (Being The Ricardos)

Nicole Kidman's Academy Award-nominated portrayal of Lucille Ball in 2021's Being the Ricardos was achieved with more than just makeup. The actor shed her Australian accent and added a smokiness to match the I Love Lucy star's natural voice but was also challenged to imitate the more high-pitched tone of the comedy icon's onscreen alter ego.

Melissa Rauch (The Big Bang Theory)

Dr. Bernadette Maryann Rostenkowski-Wolowitz easily boasts one of the most impossibly high-pitched voices in sitcom history. However, The Big Bang Theory cast member Melissa Rauch actually sounds nothing like Howard Wolowitz's bride, yet maintained the façade convincingly for 10 seasons on the hit CBS comedy.

Chris Pratt (The Super Mario Bros. Movie)

Despite making "total sense" to the directors of Illumination's The Super Mario Bros. Movie, fans of the original Nintendo video game series had some initial hesitation over Chris Pratt's casting as the older Mario brother. However, the actor wisely avoided the plumber's stereotypical Italian dialect from the games in favor of a Brooklyn accent that effectively masked his natural voice.

Robert Pattinson (Mickey 17)

Robert Pattinson plays the title role of Bong Joon-ho's 2024 sci-fi comedy Mickey 17 with an entirely unrecognizable and, admittedly, kind of goofy voice. According to IndieWire, the English actor based the voice for his "expendable" character and his many clones off of comedian Steve-O.

Johnny Depp (Charlie And The Chocolate Factory)

Say what you want about Tim Burton's 2005 adaptation of Roald Dahl's Charlie and the Chocolate Factory but you have to admit that Johnny Depp did try something amusing with the role of Willy Wonka. To play the eccentric chocolatier, he adopted a high-pitched wheeze that almost makes you question if it really is the same guy who played Capt. Jack Sparrow under that top hat.
