Actor Robert Redford addressed his surprise casting in Captain America: The Winter Soldier at a Los Angeles Q&A session last night. Here's what he had to say about why he decided to join the Marvel Phase II sequel.

"I'm doing this film because it's different. It's a new thing for me. I think these films are really powerful. I think they're great. This is the kind of film I would have loved to see as a kid. I like the idea of stepping into new territory. I'm excited by it. I also think it's a good bunch of people who really know what they're doing."
