1) 9/ll films. There have been some bracing documentaries about the Sept. 11 attacks (shown here). Now, 24 years later, those films rerun on History (7 a.m. to 4 a.m.) and National Geographic (8 a.m. to 2:30 a.m.) Especially powerful are History’s “102 Minutes That Changed America” (10:04 p.m.) and Geographic’s “9/11: One Day in America” (8 p.m. to 2:30 a.m.).
2) “Celebrity Family Feud,” 8 p.m., ABC. Gymnasts have become our new reality stars. Tonight begins with two of them: In the 2024 Olympics, Stephen Nedoroscik won silver (in pommel horse) and Jordan Chiles won team gold. Next Tuesday, she’ll also be on “Dancing With the Stars,” trying to become the seventh Olympian (and third gymnast) to win.
3) “Georgie & Mandy’s First Marriage,” 9 p.m., CBS. After being bumped by a music special last week, the show returns. It’s expected to have a rerun of the second episode, a terrific one with Georgie’s sister stirring trouble.
4) “Cinderella” (2015), 7:30 p.m., Freeform. Beautifully directed by Kenneth Branagh, this is a logical lead-in to the new “Project Runway” at 10. It’s a gorgeous film that drew an Academy Award nomination for its costumes.
5) “Star Trek: Strange New Worlds” (Paramount+) and “Beauty in Black” (Netflix). One streaming show ends its season while another arrives. It’s the end of the third season for “Trek” and the arrival of the second for “Beauty.” That’s a Tyler Perry project that began with women in opposite worlds — a stripper and the head of a hair-care company.
