Mel Gibson will make a cameo in The Hangover 2 and will shoot the scene in the next 2 weeks. Riggs will play a tattoo artist in Bangkok, Thailand (where the movie will be partially set). Nothing is known of the role for Gibson, who has made his fair share of headlines (all alleged) over the last while. Whether or not it’s a parody of his real life or just playing the role of a tattoo artist is anyone’s guess. The Tyson cameo in the original movie was inspired and it would be great to see Mel not to take himself too seriously, which I don’t think he does anyway!
