Asked whether Galactus might appear in a Fantastic Four sequel, Arad said "Galactus is going to be in the Silver Surfer movie, which we're starting our journey towards."
But he said that there may be some franchise cross-pollination. "First we want to do the origin of the Silver Surfer and the Galactus story. But because it's the same studio, one day you'll probably have our version of Alien Vs. Predator - only a much, much better version."
