In a recent interview on the Live With Regis & Kelly show, Tom Welling - who played Superman/Clark Kent in Smallville, which recently ended its run on TV - reveals which specific powers of Superman that he'd like to keep. He revealed that he'd like invincibility, but would prefer x-ray vision (this is where the conversation started getting out of hand). From TV Squad:
Regis Philbin asked Welling which of Superman's powers Welling would personally like to have. Invincibility would certainly merit consideration, he said, but it might not be the most fun.
"At the same time, I think X-ray vision could be fun," he said, putting his hand on Philbin's shoulder and looking at Kelly Ripa, "especially right now." Ripa said it might not be as much fun as Welling might think. "You'd be like, 'Sir, why are you sitting in Kelly's chair?" she joked.
Smallville is no longer running on television.
