25 best movie cameos ever

The Hangover – Mike Tyson (2009)

Iron Mike's tiger-loving cameo definitely appeared to be one of the highlights when the trailer was being bandied about. When we got to see the film in its entirety, Tyson proved that some cameos should indeed be muted roles – although punching Zach Galifianakis was particularly brilliant. In his defense, he was probably high on some kind of narcotic after admitting on an ESPN radio show that he only signed up for the film to finance his drug habit! Why they bothered to recast him in part II will forever remain a mystery.
