Get out my way, pimpin'.
Only problem with Michael Jai White is that he isn't that good of an actor. He's not bad, but he's not on par with the talent Marvel has been putting in their movies.
Black Panther is a character that often makes Iron Man look like an ass. Can you see MJW pulling that off?
He's a better or as good an actor as every single Marvel lead except maybe Robert Downey Jr.
