Castle Exclusive: Lost's Mark Pellegrino Travels Back in Time For Film Noir Episode

Castle has enlisted Lost and Supernatural vet Mark Pellegrino to headline its upcoming 1940s-set film noir-themed episode, TVLine has learned exclusively.

Pellegrino will play Tom Dempsey, a ruthless club owner from 1947 who has it out for a private eye and his best girl (who Castle imagines as himself and Beckett) and whose shadowy dealings may be tied to a murder Castle and Beckett are investigating in the present day.

The trippy episode is slated to air during February sweeps, which means it’ll likely coincide with [SPOILER ALERT] Pellegrino’s one-episode return to Syfy’s Being Human.
