Best bets: Cha cha cha! ‘Dancing’ suits up

TV
Why is "Dancing With the Stars" so addictive? The celebs are C-list (that one guy from the "Sex and the City" movie, really?). The costumes are straight out of a fever dream. And the mirror ball trophy they're competing for is widely acknowledged as tacky beyond belief. Yet somehow it all comes together for some rather riveting television. Two dancers had to be replaced last-minute when Nancy O'Dell and Jewel dropped out due to injury — their replacements will be announced on the premiere. (Premieres March 9, airs Mondays at 8 p.m., Tuesdays at 9 p.m., ABC.)

To some of us, Nathan Fillion will forever be Captain Mal from "Firefly." It's nice to see him returning to TV as Richard Castle, a mystery novelist who helps the NYPD solve a murder based on his books. "Castle" was reportedly inspired by "Moonlighting" and "The Rockford Files," and if that's at all true, this is a show to watch. (Premieres March 9, 10 p.m., ABC.)

DVD
If all you know about "Milk" is that it just won two Oscars (best original screenplay and best actor for Sean Penn), now's your chance. The film is based on the life and death of San Francisco supervisor Harvey Milk, the first openly gay man to be elected to office in California. Some viewers think Josh Brolin's role as Milk's assassin, "Twinkie defense" creator Dan White, was also Oscar-worthy. Decide for yourself when it hits DVD this week. (Out on DVD March 10.)

Movies
In 1976, “Escape to Witch Mountain” made the kind of low-tech magic that tween fans of the day adored. But are today’s video-game savvy, Twittering teens ready for “Race to Witch Mountain,” the story about two alien kids (AnnaSophia Robb, Alexander Ludwig) who are being hunted by a government organization? Well, how about if The Rock (now known only as Dwayne Johnson) is involved? (Opens March 13)

Think it’s easy to get blood out of the carpet? How about brain matter off the wall? Amy Adams and Emily Blunt star as two sisters who start a business cleaning up crime scenes in “Sunshine Cleaning.” When the business finds success, the sisters find a whole new respect for each other. Alan Arkin co-stars as their dad. (Opens March 13)

Music
As you watch questionable singers like Kris Allen warble their way into the “American Idol” top 12, what better time to pick up the album of season-one winner, Kelly Clarkson? “All I Ever Wanted” marks a return to pop form for the sassy crooner. (On sale March 10)

There’s something about the name Elvis. Elvis Presley, Elvis Costello and, yes, Elvis Perkins. He may not be a household name yet, but his new album “Elvis Perkins in Dearland” offers up more of the singer’s unique folk-rock sound. (On sale March 10).
