Oscar-winning actor, screenwriter and director Ben Affleck kicked off a new week of ABC's Good Morning America with a live in-studio visit to talk about his new film which opens Friday. He stars in and directed Argo. It's a movie about liberation, about setting people free. It's based on the real-life, almost "Mission: Impossible" rescue of Americans held in the Iranian hostage crisis of 1979. Each time I've seen a photo of Affleck in Argo or watched the movie's trailer, I thought "Who does he look like?"
