2. Of the musical's songs that made it into the movie, a few of them were rearranged to better fit the vibe of the movie. This way the existing songs had more of a "cinematic music video style" and "pop style."
3. Way before playing Regina George in the movie, Reneé Rapp made her Broadway debut as Regina in Mean Girls when she was just 19. Tina said she already knew she wanted Reneé for the movie so casting her was "easy."
4. Angourie was one of the few in the cast who didn't need to audition for her role, because Tina already wanted her to play the role. She explained that one day Tina sent her an email with the script attached. Then, it took Angourie two weeks to decide if she wanted to commit to the movie because she was so nervous about taking on the role.
5. Before starring in Mean Girls, Bebe Wood, who plays Gretchen Weiners, actually appeared in an episode of 30 Rock alongside Tina Fey, back in 2012. Bebe was only 10 at the time, and Tina said that while watching her audition tape she didn't even realize Bebe was the same girl she worked with all those years ago.
6. Christopher Briney, who plays Aaron Samuels, originally passed on an audition for Mean Girls because he doesn't like to sing. Then, when he found out that Aaron didn't have to sing he happily took the role.
7. Avantika said that she was super hopeful about landing the role of Karen when she first auditioned. However, the movie's directors Arturo Perez Jr. and Samantha Jayne thought she was a "shoo-in," and they thought her audition tape was "brilliant." Three months later she was offered the role of Karen Shetty, whose last name was changed to accommodate Avantika's South Asian background.
8. Jaquel Spivey, who plays Damian, explained that bonding as a cast was really important for them and encouraged by Tina. So, one night the cast went into town together and played games for hours at a local arcade. Another time, they all got together for an Oscars viewing party thrown by Bebe.
9. Auli'i Cravalho learned to play guitar in order to play Janis. She explained that it took her a while to actually learn how to play the song "A Cautionary Tale" and that she brought her guitar with her everywhere for about two months.
10. The moment where Cady can't find a seat in class so she sits on the floor was actually improvised by Angourie Rice, and when Auli'i Cravalho, who plays Janis, first saw her do it, she burst into laughter.
11. The film was shot at Mater Dei Prep, a former Catholic high school in Middletown, New Jersey that closed down back in 2022.
12. The moment in the gymnasium where Damien pulls out his fan was improvised by Jaquel Spivey, and the moment made Reneé burst into laughter when she first saw him do it.
13. Avantika is about to turn 19 this month, and wasn't even born when the 2004 Mean Girls came out.
14. When updating the script for 20 years later, Tina Fey purposely tried to stay away from using slang because she knew that by the time the movie came out, that slang might already sound dated.
15. In fact, Tina even did away with a lot of the more problematic jokes and storylines from the original movie, namely Coach Carr's inappropriate relationship with a student and several of the insults in the Burn Book.
16. Another joke from the original movie that was taken out was Regina making fun of Janis for her sexuality. Tina explained that all these years later Regina would know that anti-gay rhetoric "wouldn't fly." "She’s going to find a way to inflict pain on people, but she’s not going to get herself in trouble," Tina explained.
17. Tina even sought out advice from her own children, Alice (18) and Penelope (12), about modern updates for the movie. One of the things she asked them about was if the Burn Book should still be a physical book or updated to be a website.
19. Christopher didn't actually meet Jon Hamm, who plays Coach Carr, on set. He explained that while Aaron is super important to the movie's plot, he actually isn't in too many scenes and spent a lot of time in his dressing room waiting to be called to set.
20. Ashley Park, who made a cameo as Madame Park, originated the role of Gretchen Weiners in the original Broadway cast of Mean Girls.
21. Angourie shared that every single day on her way to set she'd listen to "Not Strong Enough" by boygenius.
22. Filming for "Revenge Party" ended up taking weeks and was one of the more difficult montages to film. The super vibrant set design for that song was specifically meant to look like "Lisa Frank puked all over the walls."
23. Finally, Lindsay Lohan, who starred as Cady in the 2004 film, came all the way from Dubai to make her cameo in the new Mean Girls. At the time of filming, she was about seven months pregnant, too. Tina loved the idea of making her the mathlete's moderator because she felt that scene was so late in the movie that viewers would have forgotten to keep looking for cameos.
