Prison Break and Heroes actor Robert Knepper has joined the cast of Universal Pictures' supernatural comedy R.I.P.D., Heat Vision reports. Production began last week in Boston.

Based on the 2000 Dark Horse miniseries by Peter M. Lenkov and Lucas Marangon, R.I.P.D. centers on the Rest In Peace Department, a divine law-enforcement division comprised of ghosts who grapple with spirits who aren’t ready to depart this world. Director Robert Schwentke’s adaptation stars Ryan Reynolds as Nick Cruz, a recently murdered police officer who trades 100 years of service to the R.I.P.D. in exchange for a shot at finding his killer. Jeff Bridges plays his partner, a wise-cracking ghost who’s been hunting spirits since the 19th century.

Knepper, who's best known for his turn as the scene-stealing Theodore "T-Bag" Bagwell in Fox's Prison Break, will play one of the spirits not ready to move on, known in the film as a "deado." The cast also includes Kevin Bacon, Mary-Louise Parker, Stephanie Szostak, James Hong, Mike O'Malley and Marisa Miller.

Clash of the Titans screenwriters Matt Manfredi and Phil Hay penned the script. Dark Horse’s Mike Richardson will produce with Neal Moritz and David Dobkin.
