You know you're getting some good dirt on a show when it even catches some of its stars by surprise. That's what happened at Sunday's Glee session at Comic-Con, where creator Ryan Murphy hit Chris Colfer with the news that he may soon get to do "The Time Warp," the classic song-and-dance routine from The Rocky Horror Picture Show. A few other surprises? The Britney Spears episode may be a little dream-like, even if it isn't exactly a dream for one star. And get ready for more Madonna.
