What historical figure has been best represented in film?
I guess the question started when I was recently thinking again of Mightygodking's "I Should Write Dr. Strange" posts. He was discussing Dracula and pointed out some of the great actors who have portrayed Dracula in film (Bela Lugosi, Jack Palance, Gary Oldman, Christopher Lee). But Dracula's not real, at least the vampire isn't, if you're counting Vlad the Impaler as the inspiration for the Count then that's a real historical figure.
One guy I thought of was Wyatt Earp. There's Kurt Russell, James Garner (in Sunset), Henry Fonda, and Kevin Costner (a strike against Earp). That's not too shabby. There's probably someone who has done better. Anyone come to mind?
