Animal rights advocates were enraged about Crystal the Monkey’s drug dealing role in The Hangover: Part II. In the sequel, the tiny primate appears to have a bit of a smoking problem, but Warner Bros. claimed the cigarettes she smoked on-screen were unlit. However, Crystal’s controversial role was not enough to shake the veteran actress, who helped The Hangover: Part II have the highest-grossing worldwide opening for a comedy film. “She’s amazing,” co-star Ken Jeong raved told USA Today. “She’s not a monkey, she’s an actor. And quite possibly the best actor I’ve worked with.”
The adorable teenage capuchin has starred in more than 20 different films, including American Pie and another movie this summer with a primate premise, Zookeeper.
