The embattled actor will reportedly play a tattoo artist.
The film, a sequel to the 2009 hit comedy "The Hangover," is beginning production, with a release scheduled for May 2011.
The 54-year-old might be hoping some comedy improves his tarnished reputation: a memorable appearance in the first "Hangover" film helped rehabilitate Mike Tyson's image.
Authorities are investigating claims by the actor's ex-girlfriend /*Oksana Grigorieva*/ that the actor-director physically abused her. Audio purportedly of /*Gibson*/ making a series of racist and misogynistic rants was leaked earlier this year.
"The Hangover 2" follows the characters of the first film on a trip to Southeast Asia for a wedding. The first "Hangover" grossed $462 million worldwide at the box office.
