1) “Red Nose Day,” 8-10 p.m., NBC. Screenwriter Richard Curtis started this in England, as an annual fundraiser for kids’ causes, then nudged it to the U.S. For this one, he’s written a mini-sequel to his “Four Weddings and a Funeral” movie, with Hugh Grant and Andie MacDowell (shown here) and more. There’s music by Kelly Clarkson and Blake Shelton; comedy with Kate McKinnon, Rob Gronkowski and more; plus a serious film with Milo Ventimiglia (“This Is Us”) seeing overseas projects.
2) “Hollywood Game Night,” 10 p.m., NBC. The “Red Nose” night continues with a special version of this game. Clarkson will be there, with Jennifer Garner, Kenan Thompson, Kristen Bell and more.
3) “Life in Pieces,” 9:30 p.m., CBS. After three comedy reruns, CBS actually has a new episode. “Pieces” started late – it will be a mid-season show again next year — and has eight new episodes left. After a serious heart problem two episodes ago, Tim is urged to take walks with his mother-in-law. Also, Jen tries not to go into labor until after her daughter’s birthday party.
4) “Elementary” season-opener, 10 p.m., CBS. The good news is that the networks saved some scripted shows for summer. The bad news is that this opener is so-so. The personal parts are OK: After confessing to a murder he didn’t commit, Sherlock fled to London. Watson went, too, sometimes working with young Kitty Winters. Back in New York, the captain struggles with his daughter’s death. But Sherlock’s new case – like many in “Elementary” — is lame … then is resolved in a sudden blur.
5) More, cable. When broadcast networks skid into reruns, cable takes over. Tonight – alongside the Oscar-nominated “BlacKkKlansman” (2018) at 8 p.m. on HBO and the above-average “Cloak & Dagger” at 8 on Freeform, two shows premiere: Christina Anstead, now divorced, goes solo in California; “Christina on the Coast” is 9 p.m. on HGTV. And John Turturro plays a 14th-century, crimesolving monk in the eight-part “Name of the Rose,” at 10 on Sundance.
