Stanley Kowalski & Sonny Corleone

Watching Marlon Brando play Stanley Kowalski in Streetcar, I can't help but think James Caan must have watched this performance over and over taking in every inch of his perfomance as prep for playing a similar hothead in the Godfather.

Come to think of it a young Brando would have made a great Sonny Corleone too!
