Castlegrip, Christopher Brow, gave the fans another behind the scenes view of Castle in February.
He said the correctional facility, they were filming in, had been closed for years. He also said that although they were filming in a jail, the location would not be a jail in the show.
Christopher said the pole cam, they were shooting with, would be used as surveillance footage.
