TOM CRUISE FOR GRAY FOX!
Agreed on LS, not on Sean Connery. Don't get me wrong: Sean Connery slaps Chuck Norris just to wake his hand up in the morning. But don't you think a distinctly American character would have a hard time coming across from someone with such a distinctive accent?
Big Boss is based on sean connery for christ sake, it would be like if sam jackson didnt play nick fury.

Nick Fury is only even black in Ultimate Universe, so it depends which Nick Fury.
Also, I know his appearance was, but unless they dub over him (blasphemy of biblical proportions) it will be hard to say "Yeah, this guy is an American hero, and killed his own master for the USA." while he sounds like Sean Connery.
