Photos: Iron Man suits up in CGI

Hal Hickel -- who won an Oscar for visual effects for his work on Pirates of the Caribbean: Dead Man's Chest -- dealt with things like figuring out how to make Iron Man's flying motions feel right to the audience.

"It ended up being really challenging, the flying," Hickel said, "figuring out how he should fly. Iron Man takes off slowly like a heavy object, and then lands very fast because he weighs a lot."
