1) “Saturday Night Live,” 11:29 p.m., NBC. Kieran Culkin’s “SNL” debut may have gone unnoticed. He was 9 then and cast as Froggy in a sketch; his brother Macaulay, 11, hosted. Now, 30 years later, Kieran is the host, with Ed Sheeran as music guest. Once merely the brother of the “Home Alone” kid (they’re shown here with their movie parents), he did indie films, getting awards for “Igby Goes Down” (2002). As the troubled Roman in “Succession,” he’s drawn praise, an Emmy nomination … and this belated eturn to “SNL”
2) “Highway to Heaven,” 8-10 p.m., Lifetime. For five seasons, this thrived with Michael Landon as a guardian angel. Now, 32 years after it ended, it’s a series of movies. Jill Scott is better-known as a Grammy-winning singer-songwriter, but she was terrific in HBO’s “No. 1 Ladies Detective Agency” series. She plays the angel, with Barry Watson (“7th Heaven”) as the only mortal who knows her secret.
3) More movies. There are other magical helpers tonight: Caroline Rhea stars in “A Mrs. Miracle Christmas,” at 10 p.m. on Hallmark Movies & Mysteries; Christopher Lloyd and Lea Thompson have a time-travel film in “Next Stop, Christmas” (8 p.m., Hallmark) … just as they did in “Back to the Future.” For a totally different tone, the “Attica” documentary is 9 p.m. on Showtime. It’s from Stanley Nelson, who has directed brilliant documentaries on the Black Panthers, freedom riders and more.
4) “Bull,” 8 p.m., CBS. A scientist has been charged with a series of anthrax attacks; Bull suspects police moved too quickly, arresting her to calm public hysteria. That rerun is followed at 9 by an “NCIS: Los Angeles,” with Navy and CIA officers being murdered.
5) Sports rush. Baseball has finally finished (just ahead of the snowflakes), but now there’s horse-racing to compete with college football. NBC has the Breeders Cup at 8 p.m. ET; at 7:30 ET, it’s Oregon (ranked No. 4) at Washington on ABC and Indiana at Michigan (No. 7) on Fox. The day’s best match-up may be Auburn (No. 13) at Texas A&M (No. 14), at 3:30 p.m. ET on CBS.
