Mark Pellegrino has landed another major guest-starring role.
The Lost/Being Human/The Closer/Supernatural actor will appear on an upcoming episode of Castle, TV Line reports.
Pellegrino will portray a club owner named Tom Dempsey in a February Sweeps episode that takes us back to 1947. It will feature a unique, fantasy-type flashback by Castle, along with a present day murder investigation.
Castle is on hiatus until January. It recently hired Justin Hartley and Hilarie Burton to guest star in another unique episode, one based around a talentless reality star.
