Leonardo DiCaprio's latest film is called The Wolf Of Wall Street, but it's a chimpanzee that's making headlines after the actor consented to scenes with a trained primate. Animal rights organization PETA slammed the star last week for allegedly perpetuating animal cruelty, and revealed today that more than 40,000 fans have signed a petition taking DiCaprio to task for his actions.

DiCaprio acted with the ape, named Chance, in a scene that shows a raucous party in his characters stock brokerage.
