Mike Hughes on TV

1) “The Walking Dead: Dead City,” 9 p.m., AMC, rerunning at 10:01. More than other shows, this covers the full range. It’s sometimes gory and brutal, sometimes surprisingly warm and deep. This hour leans toward the latter, with quietly moving moments for Maggie and Luis (Lauren Cohan, shown here, and Raul Castillo). Then the final minutes are sensational. Read more…

1) “Saturday Night Live,” 11:29 p.m., NBC. This reruns the May 2 episode, with Olivia Rodrigo (shown here at a concert) doubling as host and music guest — something only two other people (Harry Styles and Sabrina Carpenter) did this year. At 23, she’s one of the youngest people to double up; Britney Spears set the record, at 18. Read more…

1) “The Front Page” (1974), 9:45 p.m. ET, Turner Classic Movies. A great, three-day stretch begins for TCM. Natalie Wood and Cary Grant marathons are Friday and Saturday, but first is Jack Lemmon. He links with Walter Matthau (shown here, left) for two terrific comedies, thi one and “The Fortune Cookie”) at 3:30. The tender “The Apartment” is 5:45, with “Some Like It Hot” at 11:45. Read more…

1) “The Americas,” 8 and 9 p.m., NBC. The first rerun (with “fun facts” added) visits the Caribbean, with its 7,000 island; there are compelling views of red crabs marching to sea, across a busy (and lethal) road. The second tells how this series got its great footage, including this view of flamingos in the Andes. Read more…

1) “Nation’s Dumbest,” 9 p.m., Fox. The rest of this season is a search for the second-dumbest. Carmen Electra (shown here) has already proved herself as the bottom of the class. She failed frequently, was late for one test, skipped another and last week was “expelled.” She said she was brave to try the show, “not knowing so much stuff.” Jon Heder, who knows lots of stuff, won the round.

1) “America’s Got Talent,” 8-10 p.m., NBC. The callbacks began last week, with Simon Cowell and Mel B each re-seeing six acts. He sent five (three singing, one dancing, one comedy) to the live shows that will start Aug. 18; she sent three (two singing, plus a mentalist duo). Now Howie Mandel and Sofia Vergara (shown here, left and with arms raised, in a previous season) have their turns. Read more…
