1) “Bonnie and Clyde” (1967), 8 p.m. ET, Turner Classic Movies. In real life, Clyde Barrow was an ex-con who met Bonnie Parker, a 19-year-old waitress with an estranged husband. They launched a three-year crime spree; despite murders (including nine lawmen), their five-person gang became Depression celebrities. That’s captured brilliantly in this film, which drew 10 Oscar nominations, including its stars (Warren Beatty and Faye Dunaway, shown here) and best picture.
2) “Flowers in the Attic: The Origin,” 8 p.m. and midnight, Lifetime. After scoring in 2014 with a “Flowers” remake (which reruns at 6 and 10:04 p.m.), Lifetime made three sequels. Now a prequel tells us how Olivia (the “Flowers” grandma) became so cruel. Here, she’s a brainy businesswoman (Jemima Rooper), courted by a rich guy (Max Irons); Kelsey Grammer and Paul Wesley appear briefly. The result is richly filmed, but unrelentingly dreary.
3) “Generation Gap,” 9 p.m., ABC. If you missed Thursday’s debut, here’s a quick second chance, with kids and their grandparents answering questions about each other’s generations. Other ABC reruns have a Mother’s Day edition of “America’s Funniest Home Videos” at 8 p.m. and “The Rookie,” with Nolan helping a bounty hunter on his first case, at 10.
4) “Transplant,” 8 p.m., NBC. Bash helps an angry man during his commute. He’s been a hero in Toronto, using makeshift skills he learned helping Syrian rebels. Then he learns bad news, in his effort to get his medical-school transcripts. That sets up next week’s busy and involving season-finale.
5) “Saturday Night Live,” 11:29 p.m.,, NBC. This reruns Jake Gyllenhaal’s second turn as host – and his first in 15 years. Camila Cabello is the music guest.
