Point of Origin (HBO, 8-10 p.m.): Ray Liotta stars in a bizarre psychological thriller about a fire investigator pursuing a serial arsonist whose crimes escalate as they continue. The investigator believes the arsonist is mocking him, drawing closer and closer to his family. A creepy twist in the plot leads down some dark corridors of the mind. Liotta makes an intense nerd in this taut and scary story. Adult situations and rough language.
Croc Week (Animal Planet, through June 29, 8-10 p.m.): The Crocodile Hunter (Steven Irwin) is back, as brazen as ever, and this week includes not only three new wild adventures, but a sneak peek at his feature film, "Crocodile Hunter: Collision Course." You have to love a guy who appreciates animals so dearly.
Music Behind the Scenes (Bravo, 10-11 p.m.): Ever wonder how music in a movie affects your understanding of the action and ideas? Bravo dedicates the summer to a promising series about music in the movies. The first episode is "Humor," beginning with Charlie Chaplin's goofy sound effects. It goes on to explain how Henry Mancini made one of the most memorable comic scores ever for "The Pink Panther." Other movies include "Beverly Hills Cop" and "The Full Monty."
Diana: The Interview and Diana: The Wedding Story (BBC America, 8-10 p.m.): Princess Di's story runs through the summer. "The Interview" (recorded in November 1995) changed public perception about the troubled royal marriage. "The Wedding Story" brings back the fairy tale romance and the fantasies of a generation. The series continues June 30 with "Diana: Story of a Princess," and Diana: Her Life and Death" (Aug. 4).
Lift (Showtime, 8:30-10:30 p.m.): A passable movie about a beautiful African-American shoplifter who will do anything to win the approval of her emotionally distant mother. The best thing about the piece is Kerry Washington's performance. But Lift is not particularly up-lift-ing.
Frontline (PBS, check local listings): The award-winning documentary series outlines the conflict between Israelis and Palestinians. The facts are here as well as a few illuminating interviews. But many questions are left unanswered.
