TV’s best bets: Singer Minogue guests on ‘Doctor Who’

Tonight’s might-see

“Doctor Who,” 8:30-10 p.m., Sci Fi Channel.

Well, why not start a season (in April) with a Christmas episode? That happens here, with what “Doctor Who” officially calls “Season 4, Episode 0.”

The Doctor is racing through space in his ship, which looks a lot like an English telephone booth. It collides with a ship that looks a lot like the Titanic.

This happens in the midst of a Christmas party. (In England, this aired on Christmas Day.)

The Doctor must save the crew and the planet, with the help of a waitress named Astrid Peth. She’s played by Australian pop singer Kylie Minogue.

Other choices include

“Desperate Housewives,” 8 p.m., ABC. Here’s a rerun of Sunday’s episode, the first post-strike one. Neighbors learn Katherine’s secrets. Also, there’s a surprise wedding, plus the arrival of Susan’s handsome cousin (Chris Carmack).

“Confessions of a Teenage Drama Queen” (2004, Disney Channel) or “Jurassic Park” (1993), TNT; both 8 p.m. Fridays are a night for pop movies aimed at a broad audience. Disney has Lindsay Lohan as a teen who moves from Manhattan to New Jersey; TNT has Steven Spielberg’s dinosaur film, with screams and scares.

“Canterbury’s Law,” 9 p.m., Fox. The season finale has Elizabeth trying to avoid defending a rapist in court.

“Lone Rider” (2008, Ion) and “Avenging Angel” (2007, Hallmark), 9 p.m. Two cowboy films have regular guys turn to vengeance. “Lone” has Lou Diamond Phillips as a former soldier; “Angel” has Kevin Sorbo as a former preacher.

“Numb3rs,” 10 p.m., CBS. In this rerun, robbers take a valuable comic book.
