Mike Tyson

"The Hangover"
In 2009, Tyson went a long way towards rehabilitating his image when he appeared as himself in the Warner Bros. comedy The Hangover. In the film, he is able to remind audiences of his boxing prowess, by knocking out Zach Galifinakis' character in one lightning punch, and show his sensitive side as a fan of Phil Collins and the owner of a lap dog and an attractive, though dangerous feline.
