Matthew McConaughey has no recollection of doing 'full frontal' in his new movie

You'd think that most famous actors would remember if they'd filmed a full-frontal nude scene. Not Matthew McConaughey, though.  Stephen Colbert asked McConaughey about his upcoming movie Serenity, and noted that the Oscar-winning actor is "buck naked in this movie." "That's what I keep hearing!" McConaughey replied.  "I know I was topless, and I've had people coming up saying: 'Oh my God it was great to see you full frontal,'" the actor explained, shortly before he and Colbert cracked open a bourbon. "What? Was it really?" He said he was going along to the premiere where he'd find out if there was a new cut of the movie that he hadn't already seen.  Read more...More about Movies, Matthew Mcconaughey, Stephen Colbert, Culture, and Talk Show
