An anonymous scooper for Ain't it Cool sheds new light on the alleged scene that links the 'Incredible Hulk' movie to the 'Iron Man' movie. Both movies are said to feature a cameo appearance by Samuel L. Jackson as Nick Fury, which serves as a prelude to the proposed 'Avengers' movie.
Writes the scooper:
So the scene that was shot was for the Hulk with General Thunderbolt who is very important to the Hulk. Anyway, Tony Stark meets with him - which of course is a straight prelude to the Avengers Movie.
