New Iron Man 2 Trailer!

A better look at Sam Rockwell, Don Cheadle and Scarlett Johansson in Jon Favreau's sequel.

A new Iron Man 2 trailer has been released, giving us a better look at Sam Rockwell, Don Cheadle and Scarlett Johansson's characters.

Moon star Rockwell is a dastardly Justin Hammer, who recruits Mickey Rourke's justifiably over-the-top Whiplash. Don Cheadle takes over from Terrence Howard as Iron Man's sidekick War Machine, aka Jim Rhodes, while Gwyneth Paltrow's Pepper has her eye on Johansson's Black Widow.

The new look doesn't have the same visceral thrill as the first, probably as it features less of Robert Downey Jr wisecracking as Tony Stark, but the battles between Whiplash and Iron Man, both in and out of suits, is going to be epic.

Jon Favreau's Iron Man 2 is released on 30th April.
