Nice point.

Michael Rosenbaum?
Would have been perfect.

Jason Statham would've been perfect.

"I always wondered why Vin Diesel wasn't considered" What? Vin Diesel was concidered as agent47 but it brought massive criticism from the fans so in the the end he was casted out.

I always wondered why Vin Diesel wasn't considered. In a strange way I think Patrick Stewart would have been good as Agent 47 too, although obviously too old.
"A lot of Christians wear crosses. You think when Jesus comes back he'll EVER want to see a cross?"

Michael Rosenbaum?

HmmmI don't know about Vinnie as Agent 47. I feel that he is to much of a "thug". Agent 47 is a character who is covert and does not necessaril5b4y rely on brute force to accomplish his objectives. Agent 47 has the ability to blend in to his surroundings and must be somewhat physically indistinguishable.
That being said, Vinnie would be easily distinguishable, brute, and therefore, not able to be easily covert. I think 47 was cast satisfactorily as portrayed by Timothy Olyphant. I would agree that maybe he may not have been my first choice. Something about his persistent smug smirk that I don't like, however, he is a decent actor and I cannot imagine anyone else who resembles Agent 47.
The only other actor I can think of off the top of my head would be Val Kilmer. I feel that he is a talented actor (his portrayal of Doc Holiday should go down in history as one of the finest performances in film), but once again, he does not resemble Agent 47.
