Encore's all-day marathon of "Jaws" movies gives you every excuse to stay out of the water and enjoy the original classic (11:40 a.m. and 7 p.m.), but you also get to revisit two "disaster" films -- in more ways than one. "Jaws III" (7:50 a.m., 3:50 p.m. and 11:05 p.m.) finds Dennis Quaid taking on the toothed one, while "Jaws: The Revenge" (10:05 a.m., 5:30 p.m. and 12:45 p.m.) features Michael Caine, who missed picking up his Oscar for "Hannah and Her Sisters" because he was too busy filming the flop.


"The Secret Life of an American Teenager" (7 p.m., ABC Family) has a not-so-secret new gal pal: Bristol Palin. The most famous teen mom of the past few years makes a guest appearance as herself, leading us to hope that she'll have her own CW sitcom by the time her child is in kindergarten.


You may not know it, but Jeff Goldblum is a pretty decent piano player, so it's fitting that "Amadeus" Oscar winner F. Murray Abraham would play his father on the season finale of "Law & Order: Criminal Intent" (9 p.m., KARE, Ch. 11). We'd love to watch them perform a duet, but something tells us there will be too much criminal mischief for a version of "Baby Grand."


David Suchet serves as a splendid Hercule Poirot, as he proves once again in Sunday's "Murder on the Orient Express" adventure, but he also turns out to be a charming tour guide. "David Suchet on the Orient Express: A Masterpiece Special" (7 p.m., KTCA, Ch. 2) may sound like a promotional reel for the upcoming "Masterpiece Theatre" movie, but it's really more about the legendary train and Suchet's glee toward everything from the late-night bar to the chance to actually conduct the operation. I don't think I would want to travel with Poirot, but I'd happily sign up to zip through Europe with Suchet.


Due to the "Community" marathon, you won't be able to get your regular fix of Steve Carell on NBC -- unless you stay up late. The star, who has confirmed that the upcoming season will be his last, visits "The Tonight Show With Jay Leno" (10:35 p.m., KARE, Ch. 11) to promote his new animated film, "Despicable Me," but something tells me Leno's hard-hitting investigative instincts will lead him to ask some "Office" questions.
