Robert Downey Jr.: 'Iron Man 2 Incredibly Risky'

From Collider.com

"(Iron Man 2 is) incredibly risky and artistic for a big genre movie."

"The set pieces have to do with things that aren't your typical bad guy conflict. The relationships are very complex and hilarious."

"The motivations Tony has and why he turns around and does things has completely to do with his own internal processes... we're kind of trying to tell a story about how a dysfunctional family saves life on Earth as we know it."

Robert Downey Jr. said that he's taking the movie more seriously than any other movie he's ever done, and also that Gary Shandling has joined the cast to play a Senator.
