Noah Wyle is back on call. The ER alum plays Dr. Evans, a mad scientist in Davenport's secret laboratory, on the Dec. 2 ­episode of the Disney XD sitcom Lab Rats.

"My kids are huge fans of the show," says the actor, who also stars on TNT's Falling Skies. "The older they get, the more I try to impress them, so I jumped at the chance." And what could be more impressive than saving the world from gamma rays? Says Wyle, "I can't wait to see how the episode turned out."
