Batman could probably pull this off, but some of the actors sucked ass in the role, so not nearly as cool. Superman is missing it's icon, but most of the supermen are decent. The Hulk has a quality cast, could be very good.
since tom cruise is the multiverse tony stark, it would only make sense that white rhodey be played by his wingman goose.
Terrence Howard …. Seriously though they should do a multiverse thing with Howard and Cheadle and open the question if Iron Man 1 and the rest are in different universes. Just retcon the whole damn series after Iron Man 1.
