It would be hard to completely capture the grandeur of the Hulk in the body of any man, no offense Lou, and this especially rings true for today's video game and action movie-oriented society. Thus, when it comes to the Hulk CG is the only viable option. However, I echo Muril's questioning why this character was revisited in his own movie (as an Avenger would be a different story) prior to so many others.
Looking forward to Wolverine though!!!
