Robert Knepper has signed on for The CW's Cult.

The former Prison Break star will join Jessica Lucas on the upcoming pilot, which centers on a TV show within a TV show, also titled Cult, on which Lucas' character works as a production assistant and Knepper's Roger Reeves is the lead actor, portraying a deranged cult leader on screen.

Following a rash of violent crimes, Lucas' assistant will team up with an uncast blogger to determine if the crimes are based on the series.
