Fichtner will track down the escaped convicts

Devoted "Invasion" fans may still be lobbying for a reprieve, but one of the show's stars has snagged a key role on "Prison Break."

William Fichtner has signed on to torment America's favorite convicts, joining the FOX drama as an FBI agent entrusted with tracking down the escapees.

As fans of "Prison Break" recall, the show's first season ended with our heroes -- including those played by Wentworth Miller and Dominic Purcell) -- going on the lam. What, you expected the government to just let them go? The manhunt, led by Fichtner's character, will be one of the centerpieces of the second season, which just began production in Texas.

Fichtner spent last season starring as Sheriff Tom Underlay on ABC's "Invasion," which generated a passionate, but small, following before its cancellation in May.

The intense character actor's movie credits include "Go," "The Longest Year," "Ultraviolet" and the upcoming "Blades of Glory."
