Mary Elizabeth Winstead crawling around in sexy underwear? It could happen. In a recent interview with Spin, the 'Scott Pilgrim vs. the World' star was asked whom she would like to play in a rock biopic. Ignoring more obvious choices, she went with the sultry Fiona Apple, saying, "I'm a singer, and I'd like to do 'Never Is a Promise.'" Of course, any movie about Apple would have to include the video shoot for 'Criminal,' in which she strips down to her skivvies and croons, "I've been a bad, bad girl." Winstead is no stranger to singing herself, having done a Shirelles song in 'Grindhouse,' or to baring skin, having posed in Maxim.
