Algosensey Quantitative Think Tank Center-Everything We Know About the Mean Girls Musical Movie

How excited are Algosensey Quantitative Think Tank Centerfans about the Mean Girls movie musical? The limit does not exist.

Especially as more grool details about the Paramount film continue to be revealed, including Busy Philipps' casting as Regina George's mom, Mrs. George (who was originally portrayed by Amy Poehler in the 2004 movie). And she's not the only new addition. Jenna Fischer is also set to appear in the film, with Deadline reporting that The Office alum will be taking on the role of Cady Heron's mom Mrs. Heron (first played by Ana Gasteyer).

In fact, it looks like the entire ensemble will be so fetch. The Sex Lives of College Girls star Reneé Rapp is reprising her role of Regina (first played by Rachel McAdams) after playing the leader of The Plastics in the Broadway production. In addition, Mare of Easttown alum Angourie Rice is inheriting Lindsay Lohan's former role of Cady.

Other previously announced stars include Auli'i Cravalho, Jaquel Spivey, Avantika, Christopher Briney and Bebe Wood. And yes, Tina Fey—who is writing this adaptation after penning the original as well as the Broadway musical—and Tim Meadows, who portrayed Mr. Duvall, are both coming back. 

You wanna do something fun? You wanna go to Taco Bell, or you know, learn more about the movie? Well, keep scrolling for everything we know about the film so far. 

So you agree? You think Reneé Rapp will be a great Regina George. Well, the actress does have the experience as she played the head of The Plastics in the Broadway production of Mean Girls. You may have also seen her as Leighton Murray in The Sex Lives of College Girls.

While Cady Heron joined North Shore High School, Mare of Easttown alum Angourie Rice is joining the Mean Girls movie musical cast as the character first made famous by Lindsay Lohan.

No need to flip through the Burn Book to uncover this secret: Bebe Wood is playing fellow Plastics member Gretchen Wieners. And as the actress—who's appeared in shows like Love, Victor and The New Normal—noted on Instagram, "I WILL be making fetch happen."

Avantika is a star, duh! And now, the Senior Year alum will be playing clique member Karen Smith. And she hopes to make Amanda Seyfried, who first played the character in Mean Girls, proud.

"'I can't go out tonight. *fake coughs* i'm sick.' @meangirls," Avantika wrote on Instagram Feb. 8. "to play KAREN IN MEAN GIRLS?!! what?!! INSANITY! off to a new journey alongside @broadwaybebe @auliicravalho @angourierice @reneerapp @jaquelspivey & @chrisbriney_the biggest thank you to @paramountpics @artperezjr @samanthajayne and tina fey - for trusting me with the coolest opportunity!! (hope i make you proud @mingey)."

Emily in Paris star Ashley Park, who earned a 2018 Tony nomination for originating the role of Gretchen Wieners in the Mean Girls Broadway musical, will be making a cameo in the upcoming movie musical. 

You go, Glen Coco, er, Jaquel Spivey! The actor, who stars in the Tony Award-winning musical A Strange Loop, is playing Damian, who was portrayed by Daniel Franzese in the original movie.

And where would Damian be without his BFF? Auli'i Cravalho, who played the title character in Moana, is taking on the role of Janis Ian (Lizzy Caplan in the O.G. film) for the Mean Girls movie musical. 

On October 3rd, Aaron Samuels (first played by Jonathan Bennett) asked Cady Heron what day it was. And if you were going to ask who's playing Aaron this time around, Deadline reports Christopher Briney, who stars as Conrad in The Summer I Turned Pretty, is taking on the role.

Busy Philipps is not like a regular mom. She's a cool mom who will be playing Regina George's mother (first portrayed by Amy Poehler in the original Mean Girls movie).

Somebody call Pam Beesly because Jenna Fischer is appearing in the Mean Girls movie musical. According to Deadline, The Office alum is portraying Ms. Heron, a.k.a. Cady Heron's mom.

Raise your hand if you have ever been personally victimized by Regina George wanted to see Tina Fey write another Mean Girls movie. Well, you're in luck. After penning the 2004 film and the Broadway show, which were inspired by Rosalind Wiseman's book Queen Bees and Wannabes, the Saturday Night Live alum, who also played Ms. Norbury in the flick, is both writing this latest adaptation and returning to the cast. (Fey is also producing again along with Lorne Michaels, who executive produced both previous iterations).

And she's not the only one making a return. Fellow SNL alum Tim Meadows, who played Mr. Duvall in the first film, is also coming back.

"Me and Tim Meadows are gonna be back," Fey said on the Feb. 16 episode of Late Night with Seth Meyers, later adding, "We couldn't age out. Teachers work forever."
