1) “Tutankhamun: Allies and Enemies,” 8 and 9 p.m., PBS. It was 100 years ago (this Saturday, Nov. 26) that Howard Carter chiseled a peephole. “Can you see anything?” his patron asked. The reply: “Yes, wonderful things.” After five years, he had found the tomb of King Tut (depicted here); 5,398 objects, mostly gold, were there. This film looks back and leaves questions: We still don’t know who was Tut’s mother, how he died or whether this was meant to be his tomb.
2) “Secrets of the Dead,” 10 p.m., PBS. TV prefers to visit Egypt’s grand and golden times. This hour, however, goes the opposite way: Archaeologists examine a mass grave that goes back to the collapse of the Old Kingdom, when political infighting and climate changes ended centuries of prosperity.
3) “Planes, Trains & Automobiles” (1987), 6 p.m., AMC, rerunning at 8, 10 and midnight. On a day when many people are scrambling to get home for Thanksgiving, we can savor this film that has Steve Martin desperate to do the same. He’s joined by a buffoonish stranger (John Candy), creating lots of humor and occasional warmth.
4) “A Saturday Night Live Thanksgiving Special,” 9-11 p.m.,” NBC. Here’s some more humor, in the annual compilation of past “SNL sketches,” most of them quite funny.
5) More movies, cable. Before trying its new sequel on Disney+, catch the delightful “Enchanted” (2007) at 6:30 p.m. on Freeform. A cartoon princess is transformed into Amy Adams in modern Manhattan. At 8 p.m. ET, Turner Classic Movies has the “King and I” (1956). If you want something less-cheery? Lifetime Movie Network has its “Flowers in the Attic” reboot at 6; its gloomy, four-part prequel is at 8 and 10 p.m., concluding Thursday.
