If you've seen Thor, you'll know that, as with Iron Man and Iron Man 2, there's an easter egg after the credits, a bonus scene that leads into the upcoming movie The Avengers. It turns out that Thor's director Ken Branagh didn't have a hand in it—the director of The Avengers, Joss Whedon, did.
Thor star Stellan Skarsgard talks to Empire Online (clip below) about that final scene, where his character, Erik Selvig, speaks with Nick Fury, agent of S.H.I.E.L.D., played by Samuel L. Jackson.
