CASTLE
ABC, 10:01 p.m. ET
C. Thomas Howell guest stars in tonight’s new episode, revolving around a murdered rock star. As Castle (Nathan Fillion) and Beckett (Stana Katic) are investigating, a documentary film crew that was photographing the band keeps its cameras rolling – trained not just on the remaining band members, but on the investigators as well, giving this episode a faux documentary feel. No one, however, turns the amps up to 11.
