If you've seen the new trailer for "Iron Man 2" (and if you've not, what are you waiting for?!?), you may have seen the first footage of actress Scarlett Johansson as the Black Widow. (We'd previously seen stills of her in costume, but this is the first time we've got a brief, live-action glimpse).

As the trailer makes it way around the Internet, Johansson is talking about the role as Black Widow, going so far as to say she'd be interested in reprising the role in the future--whether it's in another "Iron Man" movie or the upcoming "Avengers" film.

For the past week, reports have circulated that actors John Malkovich and Anne Hathaway had signed on for the upcoming "Spider-Man 4."

The actors were set to be play the Vulture and Vulteress and serve as the adversaries for our favorite web-slinger.

At least that's according to the rumors and reports we've heard.

Actress Rene Russo has been cast for a role in the upcoming Kenneth Branaugh-directed "Thor."

The role may be a bit of a SPOILER so if you don't want to know more, please turn back now.

Every actor has his or her dream roles.

For Sam Worthington, one of them is Steve Rodgers, aka Captain America.

"As I said, I think I'd be lynched if I played the role, but I'd kill to play it," Worthington tells MTV. "There's a headline on the MTV blog: 'Sam Worthington Would Kill To Play Captain America.'"

Apple has the new trailer for "Iron Man 2" available to view and drool over.
