With so many Christmas movies being green lit, it’s surprising there aren’t more of them along the lines of “Christmas Icetastrophe” (Syfy, 9 p.m.) the gleeful holiday horror in which an asteroid crashes into a small town just as it is about to greet Santa. It’s the network’s contribution to the tiny genera of seasonal mayhem since “The 12 Disasters of Christmas” and it has just the right pedigree, including Victor Webster from “Ragin’ Cajun Redneck Gators.” Like the princess in “Frozen,” the asteroid has the power to freeze things instantly. All they need is a comic snowman and a belting song and they’ve have a hit.
A more conventional Christmas movie is “Back to Christmas” (ION, 9 p.m.) in which a woman goes back in time to repair personal situations, but only goes back one year, possibly because of the movie’s budgetary restraints.
The second best Christmas Peanuts special is on, “I Want a Dog for Christmas Charlie Brown!” (ABC, 8 p.m.), preceding the holiday twang of “CMA Country Christmas” (ABC, 9 p.m.).
Among all this merry-making, there is still a lost child to be found on “The Missing” (Starz, 9 p.m.).
An unusual Saturday night NFL game has San Diego at San Francisco (CBS, 8:25 p.m.).
Last year’s “The Sound of Music Live!” (NBC, 8 p.m.) with Carrie Underwood gets a rerun (which of course isn’t live).
There are reruns, too, of “Bones” (Fox, 8 p.m.) and “Sleepy Hollow” (Fox, 9 p.m.).
The special “How to Make a Man” (Esquire, 10:30 p.m.), part of the magazine’s big national mentoring project, trying to create thousands of mentors for young men in the next few years, features interviews with Steve Carell, Ezra Klein, Aziz Ansari and Chris Pratt among others.
A classic 1978 episode of “Austin City Limits” (PBS, 9 p.m., check local listings) features a young Tom Waits, whose schtick at the time involved looking like he was an old Tom Waits.
Amy Adams hosts a new Christmas-themed “Saturday Night Live” (NBC, 11:30 p.m.) with One Direction as musical guest.
