Mean Girls

Mean Girls is a 2004 American teen comedy film produced by Lorne Michaels and directed by Mark Waters from a screenplay by Tina Fey. The film stars Lindsay Lohan in the lead role, with Rachel McAdams, Lacey Chabert, Tim Meadows, Ana Gasteyer, Amy Poehler, and Fey in supporting roles. The plot centers on Cady Heron (Lohan), a naïve teenager who transfers to an American high school after years of homeschooling in Africa, where she quickly befriends outcasts Janis and Damian (Lizzy Caplan and Daniel Franzese), with the trio forming a plan to exact revenge on Regina George (McAdams), the leader of an envied clique known as "The Plastics".

Fey conceived the idea for Mean Girls after reading Rosalind Wiseman's 2002 self-help book Queen Bees and Wannabes. The book describes female high school social cliques, school bullying, and the resulting damaging effect on teenagers. Fey also drew from her own experience at Upper Darby High School, in Upper Darby Township, Pennsylvania, as an inspiration for some of the film's concepts. Principal photography for Mean Girls took place from September to November 2003. Although the film is set in the Chicago suburb of Evanston, Illinois, shooting took place primarily in Toronto, Ontario, Canada. During post-production, editing was completed by Wendy Greene Bricmont and the score was composed by Rolfe Kent.
