Mean Girls is a 2004 teen comedy directed by Mark Waters.

The film stars Lindsay Lohan and features a supporting cast of Rachel McAdams, Lacey Chabert, Amanda Seyfried, and Lizzy Caplan. The film was produced by Saturday Night Live (SNL) creator Lorne Michaels. Tina Fey is the screenwriter of the film, while also co-staring as well. Fey stayed true to her SNL roots by featuring SNL cast members Tim Meadows, Ana Gasteyer, and Amy Poehler.
The film received positive reviews from critics and was a box office success, grossing $129,042,871 worldwide.
