Re: Kevin Feige says no to another Hulk Movie.
As I've said before, I think the best Hulk 2 movie would be "Banner and the Hulk vs the Leader and his gamma experiments." Banner needs both his intellect to match wits with the Leader's brain, and the Hulk's might to fight against the Leader's various weapons and experimental mutants. Have the climax be Banner/Hulk preventing the Leader from nuking an entire town to create gamma mutants.
And for extra chemistry, have Banner team up with General Ross, as while they still don't like each other, they aren't active enemies anymore. . . and Ross is the world's greatest expert at hunting down gamma mutants.
