Nude Celebs: Debbie Yeh - John C. Reilly stars as fictional pop star Dewey Cox in this parody of the increasingly predictable rags-to-riches music biopic. On his hard-knocks journey toward stardom, Dewey crosses paths with the likes of Elvis, Buddy Holly and the Beatles. Before long, Dewey is writing hits, making women swoon and doing food endorsements -- in between over-the-top moments of silliness, which producers Jake Kasdan and Judd Apatow are so adept at creating. Also starring Jenna Fischer, Nicola Helwig, Serria Bishop, Debbie Yeh.
