1) “Saturday Night Live,” 11:29 p.m., NBC. Harry Styles (shown here with Kenan Thompson) hosts and is the music guest, putting him in elite turf. The first person to do both on the same night was Desi Arnaz, 43 years ago (and 18 years before Styles was born); the most recent was Chance the Rapper, three weeks ago. Others include Sting, Drake, Ludacris and Gaga, plus the old masters (Mick Jagger, Elton John, Paul Simon) and the opposite (Justin Bieber, Britney Spears, Miley Cyrus) and more.
2) “The Voice,” 8-10 p.m., NBC. Here’s a rerun of Tuesday’s episode, which sent seven acts home. Each of the four coaches started with five acts; viewers’ votes (after Monday’s show) saved two of them and the coach savcd a third. That left eight stranded; viewers’ quick votes made one the 13th survivor.
3) “Bull,” 8 p.m., CBS. Jill Flint – who co-starred as doctors in “Royal Pains” and “The Night Shift” – returns as Diana Lindsay, who has known Bull both in romance and as a courtroom opponent. Her niece and the niece’s husband are on trial for armed robbery; she and Bull form separate defense teams.
4) “Christmas Under the Stars,” 8-10 p.m., Hallmark. Jesse Metcalfe has been a Hallmark favorite, starring in the “Chesapeake Shores” series and in movies. In this one, he’s a banker who’s fired, takes a job on a Christmas tree lot, and meets an astronomy teacher (Autumn Reeser). That’s at the same time as another new movie, “Christmas in Louisiana,” on Lifetime; both channels are all-out Christmas.
5) “Frozen” (2013), 9 p.m., Freeform. Six days before its sequel arrives, here’s the gorgeous original. Other strong choice include the neatly offbeat “Burn After Reading” (2008), at 6:21 p.m. on Starz, “Get Out” (2017) at 7 and 9:30 on FXX and “Wedding Crashers” (2005) at 9 on Comedy Central.
