He says that the movie will be "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.
Downey Jr. says Iron Man 2 will be a "risky genre movie."
"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."
Downey Jr. went on to say 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.
