At Comic-Con last week, Robert Downey Jr. gave fans a bit of insight into Iron Man 2.

For at least the second time, the actor talked about how the movie's action sequences are tied into its focus on character. He said:

Every piece of action that happens in Iron Man 2 is a direct result of a part of a character arc, including probably the biggest sequence in the first hour of the movie ... everything is a result of essentially dysfunction or mistakes made, and those mistakes, when you're Iron Man, and when you're surrounded by the kind of people he is, the ramifications are ginormous.

Iron Man 2 opens on May 7, 2010.
