An actor known for his work on "House" has signed on for his first television job since the long-running Fox drama ended, reports Deadline.com.

Robert Sean Leonard will appear in a five-episode story arc on TNT’s "Falling Skies," playing a gifted but obsessive scientist who lives underground and runs Charleston’s power grid, the story says.

"Falling Skies" also tapped actress Gloria Reuben, who will play an aide to Noah Wyle’s character. The casting reunites Reuben and Wyle, who both appeared in "ER."
