Murder on the set! It's an admittedly tired premise for a crime drama, yet there's fun to be had in this week's installment. After a soap's head writer is literally axed, Castle (Nathan Fillion) and Beckett (Stana Katic) question the cast, crew and displeased fans to nab the killer. All My Children faves Rebecca Budig and Cameron Mathison guest as, yes, sexy daytime drama stars -- and murder suspects. As always, Fillion's charms give the proceedings a lift. (ABC, 10 P.M.)
