ABC's Castle is having a little fun with star Nathan Fillion's beginnings on the soap opera One Life To Live with an episode titled "One Life To Lose." The episode, which will air this spring, involves a murder on the set of a fictional daytime drama called Temptations.

Just cast are All My Children favorites Cameron Mathison and Rebecca Budig, as well as L.A. Law veteran Corbin Bernsen, who has been popping up as a priest on The Young and the Restless for several years. Corbin will play Lance Buchanan (an obvious send-up of Nathan's One Life to Live character, Joey Buchanan), Temptations' handsome and dashing lead actor who has the reputation as a ladies' man.

Cameron plays a character named Vince Bowers; Rebecca will appear as Mandy Bronson. The intrigue involves a Temptations fan who blogs about her intense dissatisfaction with the soap's storylines.

Nathan joined One Life's in 1994, and even after his star began to rise, he returned to the soap for several guest appearances.
