Roger Moore, the longest-running 007 to date and a television star on “The Saint” (not to mention the campy buddy-spy effort “The Persuaders” with Tony Curtis), returns to the small screen in “A Princess for Christmas” (7 p.m. Hallmark). Unfortunately, it’s a long time before he shows up in this holiday bauble about a beautiful aunt (raising two spunky motherless kids) from Buffalo who finds herself in a far-off magic kingdom and sweeps a young handsome royal off his feet. Katie McGrath stars in the title role.

• The irreverent, ribald and occasionally raunchy Irish host of “The Graham Norton Show” gets a new spin off series produced especially for BBC America. “Would You Rather With Graham Norton” (10 p.m.) directly follows his talk show.

”Rather” asks celebrity guests to contemplate ridiculous and often tasteless choices. For instance, would you rather permanently lose two thumbs or a cousin? Would you rather try to land an airplane while on ecstasy or defuse a bomb while suffering a hangover? Over the course of its first season, guests will include Whoopi Goldberg, Cyndi Lauper, Stanley Tucci, Alan Cumming, Scott Adsit and Judah Friedlander.

Robin Williams, Elijah Wood, Jennifer Saunders and JLS appear on tonight’s “Graham Norton Show” (9 p.m. BBC America).

• Rich party-throwers get very demanding and we’re supposed to care on “Chef Roble & Co.” (9 p.m., Bravo). There was a time when working as a waiter-caterer was something actors did while waiting to get a job on television dramas. Now reality TV wants to create drama out of catering.

Tonight’s other highlights

• An angel saves a troubled banker (Jimmy Stewart) from desperate thoughts in the 1946 holiday favorite “It’s a Wonderful Life” (7 p.m., NBC), directed by Frank Capra.

• Michigan State takes on Wisconsin for the Big Ten championship (6:30 p.m., Fox).

• Oklahoma State hosts Oklahoma with the Big 12 title at stake (7 p.m., ABC).

• Two hours of homicide on “48 Hours Mystery” (8 p.m., CBS).

• Beetles from a far-off time cause mayhem on “Primeval” (8 p.m., BBC America).

• An aging star (Harrison Ford) finds himself trapped in a joyless sequel in “Indiana Jones and the Kingdom of the Crystal Skull” (8 p.m., Syfy).

• Steve Buscemi (“Boardwalk Empire”) hosts “Saturday Night Live” (10:30 p.m., NBC), featuring musical guest The Black Keys.
