1) “The Happy Days of Garry Marshall,” 8-10 p.m. ABC. For two years, Marshall had TV’s two most-watched shows, “Happy Days” (shown here) and “Laverne and Shirley”; the next year, he had three of the top four, adding “Mork & Mindy.” He went on to movies and more, dying in 2016 at 81. Some of his top stars – Penny Marshall (his sister) and Robin Williams – have died, but others gather here, including Ron Howard, Henry Winkler, Pam Dawber and (from “Pretty Woman”) Julia Roberts and Richard Gere.

1) “9-1-1” season-finale, 8 p.m., Fox. The series started with terrific work from Connie Britton as Maddie, a passionate 9-1-1 operator. She left – Britton had only planned to do one season – but returns two years later for this guest shot. Maddie (shown here) was one of the victims, when a train plunged off the tracks; people race to the rescue, including her ex-lover Buck. Then the second “9-1-1: Lone Star” episode reruns at 9:01.

Moms come across much better in “I Remember Mama,” at 8 p.m. ET on Turner Classic Movies. Irene Dunne and three of her co-stars received Academy Award nominations. Read more…

1) “Line of Duty,” 11 p.m., AMC. To Americans, Keeley Hawes is the star of classy PBS dramas, from “Our Mutual Friend” to the “Upstairs Downstairs” reboot and “The Durrells in Corfu.” In England, however, she often does intense crime shows. Now AMC is rerunning this terrific series. As the six-week second season begins, Hawes is a cop (shown here), suddenly getting an emergency call. The early and late scenes in this opener pack a fierce jolt; in between is a solid drama, centering on a gifted actress. Read more…
