We know that Loki, the Thor villain played by Tom Hiddleston, summons an army to besiege Earth, and rumors have long suggested that this army will shapeshifting extraterrestrials the Skrulls“  Feige, always happy to play coy, commented, "Who said they were aliens?… It’s not Skrulls, I’ve been clear about that.

Feige was a bit more straightforward in addressing the rumor that Hugo Weaving's Red Skull would make an appearance, saying, "Was Skull vaporised at the end of the movie, or thrust into another realm?" asks Feige. "That remains to be seen. It would be fun to see Skull in future, but he's not in this one."

So we've got yet more photographic evidence that Chris Evans, Robert Downey Jr., Chris Hemsworth, Scarlett Johansson, and Samuel L. Jackson are in The Avengers.  Also in the film are Mark Ruffalo, Clark Gregg, and Cobie Smulders, too.  Joss Whedon writes and directs, with post-production rumbling along for a May 4th release date.
