Superman:MTV is alluding that "Smallville" star Tom Welling may be up for the role of 'Superman' in the upcoming Bryan Singer helmed project...

Welling told reporters at Sunday's Teen Choice Awards that he's signed on for a movie but is not allowed to discuss it, fueling rumors that he will star in "X-Men" director Bryan Singer's new Superman movie. "I'm sworn to secrecy," Welling said with a smile. "It's too early." A spokesperson for Warner Bros. said the role has not yet been cast. Welling, in the meantime, will continue playing Clark Kent on the small screen. "We have a couple new characters [this season]," he said. "Lois Lane will be visiting Smallville, which keeps things interesting for Clark. ... And Clark isn't necessarily earthbound this season."

Meanwhile, 20th Century Fox has terminated its two-year deal with Singer because of the director's decision to take on "Superman," which is owned by Warner Bros. Singer and the studio had been in discussions for a third "X-Men" movie, but a deal was never finalized.
