The guy in charge of securing the movie rights really dropped the ball.
According to Kevin Feige, Marvel still owns the rights to the Skrulls, Inhumans and Sub Mariner.So when these rights were secured, they neglected to get the FF's 3 main antagonists?
Besides Doom and Galactus, what other villains were they planning on using?The Mole Man?Come on.I'll bet they don't even have the Negative Zone characters.
