In case anyone was ready to stop worry about snakes, a sequel, "Anacondas: The Hunt for the Blood Orchid," arrived in theaters this weekend. For those needing to get up to speed, here's the 1997 original, "Anaconda" (6:30 p.m., HBO) with Jennifer Lopez, Ice Cube, Jon Voight and Eric Stoltz.
"Lucky 13," a special episode of the "Rugrats" spinoff "All Grown Up!" (8 p.m., Nickelodeon) finds bossy Angelica Pickles planning the biggest birthday bash ever. But there's trouble when her rival Savannah threatens the shindig with a party of her own.
"The Missing" (9 p.m., Starz) features Cate Blanchett as a mother whose daughter has been kidnapped and Tommy Lee Jones as her estranged father in this well-regarded 2003 Western from director Ron Howard. Can they put aside their differences while they search for the girl? Parallels with the classic "The Searchers" would seem to be intentional and a reflection of Howard's lifelong interest in the genre.
Ed "Speedo" Jager is driven by a lifelong passion for stock cars, the dream of becoming a "real" race-car driver, and a simmering anger at whatever stands in his way. But despite his status as one of the top drivers on the demolition derby tour, he is also a man who, after a failed marriage, is determined to be a good father to his two sons and "to make the best of what you have." Filmmaker Jesse Moss's portrait "Speedo: A Demolition Derby Love Story" (10:30 p.m., PBS 45 & amp; 49) follows Jager through the 1999 season, culminating at the National Demolition Derby Championship.
