Exclusive: Updates on The Avengers

Hemsworth, of course, is a lock for the team film, though he still has some time before he heads back to New Mexico. 

"We start shooting in a couple of weeks," he said, "which I knew that we were going to do when I signed on for 'Thor,' but it's certainly on the forefront now as the next challenge with another big group of actors that I admire hugely. I'm very excited."

"I can't talk about that," laughed Jaimie Alexander, who portrays the warrior Sif, about her possible return to the Marvel Universe, "And the funny thing is, it's because I don't know. A lot of times they don't tell us things until the very end, so I can safely say I have no clue. It would be awesome, though. I'd be totally willing to do it."

Also confirmed for The Avengers is Tom Hiddleston, reprising his role of Loki.

"I will be [heading to Albuquerque] soon," he smiled, "That is a dead-set certainty. I'm so excited. Loki has big plans… and it's going to take eight superheroes to stop him this time as opposed to just his chunky brother."

Eight superheroes could lead to some speculation, as the cast is sure to include Hemsworth as Thor, Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Mark Ruffalo as the Hulk, Jeremy Renner as Hawkeye, Scarlett Johansson as Black Widow and Samuel L. Jackson as Nick Fury. Does the eighth hero refer to Cobie Smulders' Maria Hill, or is there still a bit of surprise casting in store? Check back with SuperHeroHype for updates as they become available.
