Mean Girls.

Mean Girls is a 2004 American teen comedy-drama film directed by Mark Waters. The screenplay was written by Tina Fey and based in part on the non-fiction book Queen Bees and Wannabes by Rosalind Wiseman, which describes how female high school social cliques operate, and the effect they can have on girls. The film stars Lindsay Lohan and features a supporting cast of Rachel McAdams, Amanda Seyfried, Lacey Chabert and Lizzy Caplan. The film is produced by Saturday Night Live creator Lorne Michaels. Screenwriter and co-star of the film, Tina Fey, was a longtime castmember and writer for SNL. The film also features appearances from SNL cast members Tim Meadows, Ana Gasteyer and Amy Poehler.At the Spring Fling dance, Cady is elected Spring Fling Queen and gives a speech to her class that her victory is meaningless; they are all wonderful in their own way and thus the victory belongs to everyone. As a symbolic gesture, she breaks her tiara and distributes the pieces to her fellow classmates. Cady makes up with Janis and Damien, reconciles with Aaron, and reaches a truce with the Plastics.
The film ends with the Plastics disbanding by the start of the new school year: Regina joins the lacrosse team as a way to channel her anger positively, Karen becomes the school weather girl (claiming that her breasts can always tell when it is raining), Gretchen joins the "Cool Asians" clique and is their biggest follower, and Cady dates Aaron as well as hanging out with Janis and Damien. Now reasonably well-liked, Cady reflects that the "Girl World" she lives in is at peace.
Production.
Though set on the North Shore of Chicago, the film was mostly shot in Toronto, Ontario, Canada at Etobicoke Collegiate Institute and Malvern Collegiate Institute.[citation needed] Notable landmarks include the University of Toronto's Convocation Hall and Sherway Gardens. Regina George's house is a home in the Bridle Path neighborhood.
