Iron Man, Thor, Captain America will be in "The Avengers" movie. Nick Fury is also a confirmed character (in fact, Samuel L. Jackson signed a contract with Marvel to star in 9 possible movies) while the Hulk could also make an appearance ( Edward Norton, however, is not yet attached to the film), possibly as a villain. Marvel is targeting a summer 2012 opening.
The good ole' Canuck will get his second solo movie, possibly about his stint in Japan.
The Silver Surfer solo movie was put on hold. The producers of FF are keen on rebooting the series after two craptastic movies. Galactus is a big giant cloud? Whose genius idea was that?
