7. Tim Meadows didn’t have carpal tunnel, but a broken hand. In the film, Tim Meadows’ character wears a cast because of severe carpal tunnel. This character trait was written in because Meadows broke his hand just before filming began and would have to wear a cast throughout shooting the movie.
8. The studio wasn’t excited about Tim Meadows and Amy Poehler being in the film. Paramount had been burned from investing in SNL movies in the past (The Ladies Man) and was cautious of having Meadows and Poehler in the film out of fear audiences would see it as “an SNL movie.”
9. Rachel McAdams drew her inspiration from Courtney Love and Alec Baldwin. McAdams character of Regina could best be described as a raging b*tch that intimidates people. Director Mark Waters suggested McAdams pull some inspiration for Regina by listening to Courtney Love CDs really loud and watching Alec Baldwin’s character in Glennary, Glen, Ross.
10. The film’s lingo stretches all the way to the White House. Mean Girls’ cult following revels in its dialogue, with the cast regularly getting hit up with quotes via Twitter, and its reach has even made it to the White House. Last year, the White House tweeted out the below photo of Bo with a reference to Gretchen’s failed attempt to coin the word “fetch.”
11. Lizzy Caplan’s character was named after SNL’s first musical guest. Caplan’s character was named Janis Ian as an homage to the musican who was Saturday Night Live’s first musical guest with Billy Preston in 1975. You can hear Ian’s song “At Seventeen” playing in the background when the girls are fighting at Regina’s house.
12. There are several “Mean” projects in development. In addition to being on TBS nearly every weekend, the Mean Girls legacy will live on through spin-off projects like a musical adaptation and possible male-centered project. Writer Sean Anders (We’re The Millers) has already penned Mean Moms, which essentially shows that the cut throat landscape of high school transitions right into adulthood thanks to competitive parenting.
