CASTLE Preview: January 3 on ABC

"Nikki Heat" - Castle's novel "Heat Wave" is being turned into a movie, and the Hollywood hottie cast as the movie's lead shows up at Beckett's invitation to better understand the character she's going to play. Laura Prepon ("October Road," "That '70s Show") guest stars as actress Natalie Rhodes. As our threesome investigates the murder of a high-class matchmaker, Natalie goes to extremes in the name of "character research," transforming herself into the spitting image of Beckett -- much to Castle's delight and Beckett's dismay. Also in the episode, Melody Thomas Scott ("Young & the Restless") and Thomas Calabro ("Melrose Place") guest star, on "Castle," MONDAY, JANUARY 3 (10:01-11:00 p.m. ET).
