Emmy- and Golden Globe-winning actor James Brolin has been tapped to play the elder Castle, has learned. Although details about his character and background are being shrouded in mystery, we do know that Brolin's character will figure into the second half of next month's two-parter.

"I would not characterize the two-parter as being about his dad," creator Andrew W. Marlowe previously told "Hopefully we can find a great and elegant way to embrace Castle's father's mythology in a way that's going to be exciting."

In the two-parter's first installment, Castle (Nathan Fillion) and Beckett (Stana Katic) team with an FBI agent (guest star Dylan Walsh) to investigate a murder that exposes a plot to kidnap the daughter of a wealthy Middle Eastern businessman. In the conclusion, Castle's involvement in the case will suddenly put his life in danger.

Although Castle grew up not knowing - or caring - who his father was, his interest was piqued last season when his former muse Sophia (guest star Jennifer Beals) hinted that Castle's father had enough clout to help get his son access to the CIA. If Castle's dad is indeed involved in this international caper, perhaps Sophia's theory about his involvement with law enforcement holds water.

Brolin, whose previous TV credits include Marcus Welby M.D., Hotel and The West Wing, should know a thing or two about playing an estranged father: He will also play the long-lost dad of Community's Jeff Winger this season. His other recent TV credits include guest spots on Law & Order: SVU and Psych.
