Pretty Persuasion (2005)

Kimberly Joyce, an insanely intelligent, wildly funny, shockingly cruel and sexy-beyond-her-years Beverly Hills teenager will stop at nothing to become famous. Believing the world is an orchestra and she is the conductor, Kimberly masterfully manipulates all those around her. She convinces her two best friends to join her in a campaign against their befuddled teacher, Mr. Anderson. Kimberly entangles the entire Beverly Hills community in her carefully woven web of seduction and deceit.
