The Hangover 2 has nabbed a huge star to perform a cameo that could rival Mike Tyson’s Hangover appearance.

Mel Gibson will be appearing in the sequel, though not as himself. Gibson will be playing some sort of over-the-top character in the film. Sources say he's been cast as a tattoo artist in Bangkok.

Mel's cameo raises a lot of questions: How many of his own well-publicized personal problems will be openly mocked in the film … and how will audiences react? Unfortunately, we will have to wait until May 26 to find out.
