'Smallville' ponders Kristin Kreuk's possible return for final season

After the "Smallville" panel at San Diego Comic-Con on Sunday (July 25), Zap2it spoke to the cast and the executive producers.

In the final season, Clark (Tom Welling) will be making his final stride to earning the "Superman" title. Along the way, he'll deal with some demons, though.

"Not only are we exploring some physical and actual ghosts from the past," says executive producer, Brian Peterson. "But there are some metaphorical ghosts we are exploring as far as his inner turmoil."

One ghost from Clark's past seemed to keep popping up in our conversations with the producers and the stars. Will Kristin Kreuk, who played Clark's original star-crossed love interest, return?

"We'd love to have Kristin back, but like a lot of actors, she's very busy," says Peterson. "And, so we have some thoughts. We have the door open. Right now, that hasn't happened to work out. We want her back. We love her."

Kreuk left the show in 2008 as her character's tumultuous relationship with Clark ended with her being, well, walking kryptonite. Since then, she has appeared on "Chuck." Her agent has denied recent rumors that she'll return, though.

When we spoke to "Smallville's" star, Tom Welling, he tells us he had a scene in mind in case Kreuk does sign on.

"A great scene, I think, would be to get Clark, Lois and Lana together. And then like, 'Um, sooooo?'" As he looks around and laughs.
