Harry Potter and the Chamber of Secrets 8 p.m. on (CTV) 9 p.m. on (ABC-B) A mysterious force threatens Hogwarts School of Witchcraft and Wizardry in the totally captivating second movie adapted from J.K. Rowling’s novels, again directed by Chris Columbus. Harry, Ron and Hermione (Daniel Radcliffe, Rupert Grint, Emma Watson) must find out what is causing people known as Mudbloods to become petrified — or the school will be closed. Robbie Coltrane, Kenneth Branagh, Maggie Smith, Alan Rickman and Richard Harris co-star in the 2002 tale. The Millers 9 p.m. on (CBS-B) “Highway to the Manger Zone” is a new episode clearly airing much later than intended. The Millers devise a nativity-scene re-creation by putting their own spins on it — which does not sit well with other members of their church. Unhappy with that rejection, they consider following Kip’s (Sean Hayes) suggestion to stage their own show. Carol (Margo Martindale) tries to broker Christmas peace between Kip and Nathan (Will Arnett). The series finale immediately follows. Gremlins 9 p.m. on (YTV) An inventor (Hoyt Axton) buys an adorable critter from a Chinese shopkeeper (Keye Luke) and brings it home to his son, Billy (Zach Galligan). Big trouble ensues when Billy inadvertently breaks two care-and-feeding rules: Don’t get the creature wet, and don’t feed it after midnight. The former causes it to reproduce, and the latter turns the offspring into monsters, who proceed to wreak havoc on the town just in time for Christmas. Phoebe Cates, Corey Feldman and Polly Holliday also star in this 1984 comic thriller. Ouija 10 p.m. on (M1) The Hasbro toy company’s biggest movie tie-ins clearly have been the “Transformers” and “G.I. Joe” series, but the firm’s hand also is in this average (but commercially successful) horror story inspired by the title board game. A woman (Olivia Cooke, “Bates Motel”) and her friends play it to determine whether it had anything to do with her sister’s apparent suicide. Daren Kagasoff (“Red Band Society”), Matthew Settle (“Gossip Girl”) and genre staple Lin Shaye also star. Mega Shark vs. Kolossus 10 p.m. on (SPC) Illeana Douglas is a Hollywood blue blood (her grandfather was Oscar winner Melvyn Douglas) who has appeared in her own share of smart indie film and TV fare. Unless she lost a bet, it’s hard to imagine how she wound up in this very strange low-budget 2015 action-horror film that finds Earth menaced by two perils: the Kolossus, a giant Russian robot doomsday device dating back to the Cold War, and a really, really, really big shark.
