Jack Coleman has been cast on yet another TV Fanatic favorite.
The actor - who has guest-starred on The Office, The Vampire Diaries and will play a role on Emily Owens, M.D. this fall - will appear on multiple episodes of Castle as a U.S. Senator who finds himself "in conflict" with Beckett, according to TV Line.
No premiere date has been announced for Castle Season 5 yet, but creator Andrew Marlowe has said it will pick up immediately after events on the May finale and that he's committed to exploring an actual relationship between Castle and Beckett.
