Robert Downey Jr. has no equal. His performance as an egotistical, Academy Award-winning Australian star, who then masquerades as a black soldier, made movie-within-a-movie ‘Tropic Thunder’ as satirically hilarious as it was politically incorrect. Downey Jr. delivers the flat-out best performance by a white guy playing a white guy playing a black guy to ever gift the silver screen. Major props are due to those stuffy, white-haired movie critics on the gold-statue-giving committee for going against precedent, by awarding a nod to a character whose most memorable line was, ‘I’m a lead farmer, motherfucker!’
