1) Olympics. The final day of competition has lots of finals. Peacock (6-11 a.m. ET) has six in track-and-field, many of them (including women’s high jump, shown here from the 2016 games) rerunning on NBC tonight. Then there’s the live coverage of team gold-medal matches: men’s soccer, 7:30 a.m. ET, NBC Sports Network … men’s volleyball, 8 a.m., NBC … women’s basketball, 10:30 p.m., NBC … and women’s volleyball, 11:30 p.m., USA.
2) “Eden: Untamed Planet,” 8 p.m., BBC America. Last week’s episode (rerunning at 6:45 p.m. today) found surprising beauty in the Namib desert. Now comes a more-conventional Eden – Luanga, in Zambia. It’s lush and green, with stunning diversity, from rare black rhinos to 10,000 impalas. There’s great footage of two impalas, brandishing 30-inch horns as they battle for supremacy; a leopard waits for them to tire, then pounces, emerging with a major kill for her five-week-old twins.
3) “Magnum P.I.,” 8 p.m., CBS. In a rerun, a young man with a bullet lodged in his chest needs emergency surgery. Ethan asks Magum and Higgins to find him in a hurry.
4) “Star Wars” (1977), 5:47 p.m., TNT. Here’s the full trilogy, with “The Empire Strikes Back” (1980) at 8:32 and “Return of the Jedi” at 11:19. Earlier, the prequels and stand-alone films air at 2:17, 5:15, 8:24 and 11:29 a.m. and at 2:29 p.m.
5) More movies. The emphasis is on fun and/or silliness. TBS has the sleek “Crazy Rich Asians” (2018) at 8:30 p.m. Freeform has animation — the three “Cars” films (9:30 a.m. and 12:05 and 2:40 p.m.), plus “Ratatouille” (2007) at 5:10 p.m. and then the two “Despicable Me” films at 7:50 and 9:55. But for complete silliness, there’s Turner Classic Movies: “Abbott and Costello Meet Frankenstein” is at 8 p.m. ET; they meet the Invisible Man at 9:45, The Mummy at 11:30 and more.
