A sneering actor who always plays himself no matter whose bio-epic he is starring in. He says he "Becomes the person he is playing". But when he played Johnny Mollkin in the film, Footheaded blues, he was really playing Biles Corkly. The kind of guy who likes to walk a little ahead of you to blow you a kiss with his ass and hope you smell it.
He also played Hollerin' Jack Johnson, again it was really Biles again.
