Cast of Mean Girls (2024)

The 2024 Mean Girls musical adaptation brings a largely fresh ensemble to the story, with Angourie Rice leading as Cady Heron. This Australian actor took on the role originally made famous by Lindsay Lohan, bringing a different energy to the African transplant navigating North Shore’s social hierarchy. The film blends the 2004 screenplay with elements from the 2018 Broadway musical, written by Tina Fey and Nell Benjamin.

Main Characters

Angourie Rice stars as Cady Heron alongside Reneé Rapp as the feared Regina George. The Plastics round out with Bebe Wood as Gretchen Wieners and Avantika Vandanapu as Karen Shetty (notably renamed from Karen Smith). Auli’i Cravalho plays Janis ‘Imi’ike in a reimagined take on the original character, while Jaquel Spivey—a Tony nominee—takes on Damian.

Supporting Roles

Jon Hamm plays Coach Carr (replacing Dwayne Hill from 2004), and Jenna Fischer takes the role of Ms. Heron (Cady’s mom), previously held by Ana Gasteyer. Busy Philipps appears as Mrs. George (Amy Poehler’s original role). Director Samantha Jayne and co-director Arturo Perez Jr. helm this 2024 version.

Cast of Mean Girls Regina George

Rachel McAdams made Regina George one of cinema’s most quotable villains in 2004. Her performance turned the character into shorthand for teenage mean girl culture, spawning countless pop culture references. The film released April 30, 2004, under director Mark Waters.

2004 Original

McAdams brought a cutting wit and physical confidence that became instantly iconic. Her version of Regina remains the benchmark against which all subsequent portrayals are measured.

2024 Version

Reneé Rapp, known from the Broadway production of The Sex Education Files (Merrily We Roll Along), takes the crown in 2024. Rapp originated the role on stage before transitioning to film. Industry coverage confirms Rapp’s casting through multiple entertainment outlets. The adaptation reportedly emphasizes meta-humor around feminism and social dynamics, potentially giving Rapp different comedic angles than McAdams explored.

“Get in loser, we’re going shopping,” remains one of the most widely known lines from the original 2004 adaptation, underscoring how central the Plastics dynamic has remained across versions.

The implication is clear: McAdams set an impossibly high bar, and any successor must either honor the original or risk fan backlash. Rapp brings stage credentials that McAdams lacked, but the musical format reshapes the role’s requirements entirely.

Cast of Mean Girls Musical

The Mean Girls franchise now spans three distinct versions: the 2004 film, the 2018 Broadway musical, and the 2024 film adaptation. Understanding the casting requires tracking both the stage origins and the film choices.

Broadway Leads

The 2018 Broadway production launched several actors who would later appear in the 2024 film. Reneé Rapp originated Regina George on stage and carried that experience into the film version. The musical featured Erin Dilly as Cady, Barrett Wilbert Weed as Janis, and Kimberly Fairbanks Richtmyer as Gretchen on Broadway, though not all stage cast members transitioned to the film.

Film Adaptation

The 2024 film pulls from both the original film script and Broadway musical elements. Angourie Rice (Cady) and Christopher Briney (Aaron Samuels) didn’t originate their roles on Broadway—their casting represents new interpretations rather than stage-to-film promotions. Jaquel Spivey stands out as the Tony nominee bringing Damian from stage acclaim to the film adaptation. The film premiered January 12, 2024, running approximately 112 minutes—longer than the 97-minute 2004 original due to musical numbers.

Touted as “not your mother’s Mean Girls,” the updated version is described as a combination of the 2004 teen movie and the Broadway musical.

Cast of Mean Girls Main Characters

The main characters divide into the Plastics (Regina, Gretchen, Karen), the protagonist (Cady), her allies (Janis, Damian), and the love interest (Aaron). Below is how each maps across the two films.

Cady Heron

Cast of Mean Girls Teacher

Two teachers anchor both Mean Girls films: Ms. Norbury (the math teacher who spars with Regina) and Principal Duvall. These roles represent the most direct continuity between the two films.

Ms. Norbury

Tina Fey wrote the original Mean Girls screenplay and starred as Ms. Norbury in 2004. She returns in the identical role for 2024, making her the franchise’s only constant cast member besides Tim Meadows. Fey also co-wrote the 2024 adaptation with Nell Benjamin, giving her unusual creative continuity across both versions.

Mr. Duvall

Tim Meadows played Principal Mr. Duvall in 2004 and returns to the role 20 years later. MovieWeb confirms both return dates: April 30, 2004, for the original and January 12, 2024, for the new version. Meadows provides comedic grounding as the oblivious authority figure navigating the school’s social chaos. The full cast list for the new Mean Girls movie can be found at Meira Omar Hush Hush.

Production Credits Comparison

The production table highlights how the 2024 version differs fundamentally from its predecessor in format and creative leadership.

The 2024 Mean Girls adaptation faces an unusual challenge: replacing actors who defined roles for a generation while retaining enough continuity to feel familiar. Rapp and Rice carry the heaviest burden—they inherited characters already etched into pop culture. The presence of Fey and Meadows provides safety nets, signaling to nostalgic viewers that this remake respects its source. For new audiences, the 2024 cast stands on its own merits, bolstered by Broadway credentials that the 2004 ensemble lacked.

Rapp’s path forward is clear: lean into the musical numbers, embrace the meta-humor, and let McAdams comparisons fade as the film finds its own audience.
