Fast and the Furious star Paul Walker is no longer in the running to play Superman on the big screen. According to Variety, the actor bowed out on Thursday over reservations about the seven-year commitment required for the three films. That leaves just two candidates to succeed Christopher Reeve as the Man of Steel: Brendan Fraser and Guiding Light hottie Matthew Bomer. (For the latest on Bomer, click here.)
