He played Iron Man, a black man, Charlie Chaplin, and Wesley Snipes AIDS stricken best friend, but I'm certain Robert Downey Jr's best performance was as The Amazing Harold (formerly Harold the Great).
He played Batman, Iceman, Jim Morrison, and Doc Holliday, but I'm positive that Val Kilmer's best performance was as Gay Perry (also, he's gay).
He wrote Lethal Weapon, Lethal Weapon 2, The Long Kiss Goodnight, and Iron Man 3, but I'm pretty sure the best thing Shane Black ever did was Kiss Kiss Bang Bang.
It kisses, it bangs, and it entertains, but the best thing this film does is...
cocaine. Sorry I know there probably isn't any cocaine in this film, but I can't think of…
