Tom Cruise may be a huge action star, but he's always shown the ability to laugh at himself. Tropic Thunder is a great example of Cruise showing how willing he is to go for big laughs.
It's hard to forget the Oscar nominee jumping on Oprah's couch proclaiming his love for Katie Holmes. The performance seemed bizarre to many, but perhaps it points some sort of mating ritual from Cruise's home planet [Insert Scientology joke]. The newest Men in Black movie would be the perfect showcase for him to reveal why - despite his twenty-year career - he still looks as good as he did in his Top Gun days.
