The movie "Mean Girls" was written by Tina Fey. She wrote the screenplay for the 2004 American teen comedy film, which was directed by Mark Waters. The film was inspired by the 2002 book "Queen Bees and Wannabes" by Rosalind Wiseman, who wrote a sociology book on female high school social cliques and bullying. The story and characters in the film also drew on Tina Fey's own high school experiences. Rosalind Wiseman's book served as a major source, but the actual screenplay of the film was penned by Tina Fey.
