Bad Teacher (2011), directed by Jake Kasdan and starring Cameron Diaz, Justin Timberlake, and Jason Segel, is a crude and irreverent comedy about an apathetic, foul-mouthed teacher who schemes her way through life and the classroom. This cynical take on education blends dark humor, slacker attitude, and bad-behaviour comedy.
