Well yeah, besides their hair, eyes, nose, eyebrows, general facial structure, some vocal mannerisms, body build, etc.. hardly anything at all.
I give you all that, but the thing that scares me about him playing Michael is the personality. I don't see him as a guy who can realistically bring across Pacino's attitude in the movie.
I think he is more of the hothead-Sonny type (no not to be sonny) I just can't see him being cool and calm all the time and pulling it off.
