TELEVISION PREVIEW

As chilling as any horror movie, "Terror in Mumbai" (8 p.m., HBO, TV-14) recalls a cold-blooded assault on India's largest city that left 170 dead and more than 300 wounded. Airing a week before the first anniversary of the attack, the film, narrated by editor, author, TV personality and Mumbai native Fareed Zakaria, uses closed-circuit TV footage and intercepted cell phone conversations to offer a harrowing, minute-by-minute account from the point of view of victims and terrorists.

Nothing says Christmas like the voice of William Shatner. OK, maybe not. The "Star Trek" star and master of late-night poetry readings narrates the holiday special "Gotta Catch Santa Claus" (7 p.m., ABC Family). The cartoon follows the efforts of 12-year-old Trevor as he and his pals try to catch Old St. Nick during his yearly rounds. Their audacious escapades are complicated by the arrival of LeFreeze, a monster with a century-old grudge against the jolly old soul.

The computer-animated gang from a popular film franchise comes to Santa's (Carl Reiner) rescue in "Merry Madagascar" (8 p.m., NBC, TV-PG), the very first holiday special of the too-early-to-be-Christmas season. (For the record, Thanksgiving is still nine days off.)
