I still remember watching Charles Bronson in The White Buffalo
when I was a kid. Bronson played Wild Bill Hickok
(he's completely miscast but come on, it's Charles Bronson) and Will Samson played Crazy Horse.
It's one of those films that has a ton of famous names: Kim Novak, Jack Warden, Clint Walker, Slim Pickens, and John Carradine as an undertaker, the role he was born to play.
