Muppets legend Frank Oz--also known as Miss Piggy and Fozzie Bear, among others--is one of five Muppet veterans featured in the new documentary ‘Muppet Guys Talking.’ Oz directed the film--and he was, of course, one of the Muppet guys talking--while his wife Victoria Labalme produced it. They tell us about why they wanted to get the old gang together again. And the press-shy Oz talks about his directing career, his years working with Jim Henson, and what Disney failed to do when it bought the Muppets.
