13 details you might have missed in the 'Mean Girls' remake

Ashley Park, who played Gretchen Wieners in the Broadway adaptation of "Mean Girls," appears as a North Shore High School teacher.

She plays Cady's French teacher, Madame Park.

Park was the first actor to play Gretchen on Broadway, earning a Tony nomination for her performance.

Coach Carr can't spell "vasectomy."

Carr, played by Jon Hamm, teaches a class on health and human sexuality, which is ironic because he can't even spell "vasectomy" or "hormones" correctly.

Reneé Rapp's Gen Z version of Regina George ditches Rachel McAdams' millennial side part.

The 2024 remake updates aspects of the original movie for the new generation, like the wardrobe and accessories.

In the new movie, Regina is never caught with a side part — a millennial trend often mocked by members of Gen Z. Instead, she sports a middle part.

Regina's massive bedroom has a light-up sign of the word "dramatic" in a callback to the 2004 movie.

In the 2004 movie, McAdams wears a white t-shirt with the phrase "a little bit dramatic."

Karen Shetty tries on the iconic bra-revealing look from the original "Mean Girls" while searching for the perfect Halloween costume.

Karen ultimately decides to dress as a sexy mouse, duh.

Damian Hubbard references Ariana Grande during the Plastics' winter talent show performance.

Instead of "Jingle Bell Rock," the new generation of Plastics dance suggestively to "Rockin' Around the Pole." It's the same routine Regina and her minions have done for years, and Damian is over it.

When the camera cuts to him in the audience during the performance, he says, "Thank you, next."

This is a nod to Grande's song of the same name, which also served as the title of her fifth studio album, released in 2019.

The music video for "Thank U, Next" featured references to "Mean Girls," "13 Going on 30," "Bring It On," and "Legally Blonde."

TikTok star Chris Olsen has a cameo.

He's one of the social media users who discusses the Plastics' disastrous winter talent show performance online.

Megan Thee Stallion also has a cameo.

She pops up twice during the movie via videos on social media.

Megan Thee Stallion also collaborated with Rapp for the soundtrack song "Not My Fault."

At one point, Karen wears her nameplate necklace backward.

This is a nod to her being ditzy and clueless. It may also be a nod to Amanda Seyfried's version of Karen wearing a backward "K" on her chest at the spring fling in the 2004 movie.

When Cady becomes similar to Regina, she wears an initial necklace that's exactly like the one her frenemy owns.

As the movie progresses, Cady becomes shallow like the Plastics. She starts dressing like them, wearing more makeup, and being self-involved.

Mr. Duvall's office contains a framed photo of him from the 2004 movie.

Tim Meadows played the same character in the original "Mean Girls."

Regina wears a gray sweatshirt with the word "dramátic" printed in bold letters when she decides to get revenge.

This is another nod to the 2004 movie.

After Regina's mom informs her that the Kalteen bars Cady gave her result in weight gain instead of loss, Regina becomes furious.

She puts a photo of herself in the Burn Book, drops the book in the school hallway, and watches as rumors spread and chaos ensues.

When Damian and Janis catch Cady blowing off the art expo for a house party, they drive away on his motorized scooter.

This is a nod to the Broadway musical.
