I've been saying that they should have been doing this with Marvel movies for years. After all, that's what half the fun is with reading comics, to know that all these characters live in one big universe and to see how they interact with each other over the course of different films.
AICN have got the huge scoop that none other
Samuel L. Jackson is filming a one day cameo today in
Jon Favreau's Iron Man movie as the Marvel character Nick Fury! Fury is of course the former WWII soldier who turns into a James Bond like spy in the Marvel universe. AICN speculate that this cameo is a set-up to a larger continuity where the character will appear in future Marvel movies with Samuel L. Jackson playing the role. Love it. The pic on the left there is of the Ultimate version of Nick Fury... who has a striking resemblance to Jackson. Hopefully we will see some snaps sometime today!
