“Masterpiece” (9 p.m., PBS): PBS’ “Masterpiece” (formerly “Masterpiece Theatre”) moves into its weekly mystery phase with a summer of British crime thrillers. The plot thickens Sunday with the first of three “Inspector Lewis” films, starring Kevin Whately (“The English Patient”) as Detective Inspector Robbie Lewis, a working-class crime-solver teamed up with laid-back, cerebral Detective Superintendent James Hathaway (Laurence Fox, “Gosford Park”). Thereafter, “Masterpiece Mystery!” will feature three weeks of “Foyle’s War,” two editions of “The Inspector Lynley Mysteries” and two episodes of “Sally Lockhart,” set in Victorian England and starring Billie Piper (now playing the not-so-Victorian lead in Showtime’s “Secret Diary of a Call Girl”). Host of “Masterpiece Mystery!”: stage and film star Alan Cumming.

“Guy’s Choice Awards” (10 p.m., Spike TV): Gorgeous women, jocks and action flicks. Yes, it’s the second annual “Guy’s Choice Awards,” the show that supposedly caters to men with categories such as “Hottest Girl on the Planet.” A tribute to Playboy founder Hugh Hefner is scheduled.

“The Two Coreys” (10 p.m., A&E): Corey Feldman and Corey Haim are in a feud. For those of you under 21, that might not seem like such a big deal.
