Don't miss CASTLE this Monday, March 21, when Castle (Nathan Fillion; ex-Joey, OLTL) and Beckett (Stana Katic) have to solve a murder on the set of the fictional soap TEMPTATION LANE. The episode, cleverly titled "One Life to Lose," also features AMC stars Cameron Mathison and Rebecca Budig (Ryan and Greenlee) as well as former daytimer Corbin Bernsen (Y&R, RYAN'S HOPE). Budig said she was thrilled to reunite with Fillion. "We knew each other when I was on GUIDING LIGHT [as Michelle, from 1995-98] and he was always super, super sweet," Budig added. "I gotta say, it was so refreshing to see someone like that who has become so successful and has totally not changed… He was so welcoming and kind, he gave me the biggest hug and just kept saying how excited he was that we [Budig, Mathison, Bernsen and the other special guest star Jane Seymour] were there. I can't say enough about him. He's an amazing guy. He's adorable."
