Bad Teacher 2011

Elizabeth Halsey (Cameron Diaz) is a teacher who just doesn't give an F. She's foul-mouthed, ruthless, and wildly inappropriate. She drinks, she gets high, and she can't wait to marry her meal ticket and walk away from her day job teaching middle school. When she’s dumped by her fiancé, she sets her plan in motion to win over a rich, handsome substitute (Justin Timberlake) - competing for his affections with an overly energetic colleague, Amy (Lucy Punch) - but finds herself fighting off the advances of an irreverent gym teacher (Jason Segel). Elizabeth's outrageous schemes and their wild consequences will shock her students, her coworkers, and even herself.
