1) “Seven Worlds, One Planet,” 9 p.m. ET, BBC America, rerunning at 12:32 a.m. Here’s the start of a gorgeous nature show … but not the start that was expected. Each week, this focuses on one continent; it planned to start with the U.S., then switched to Australia (shown here), now facing rampant wildfire. That’s mentioned, but mostly we get stunning scenes – a rare view of a dingo hunting … the awesome expanse of the Aussie desert … and sharks herding swarms of fish toward shallow-water death.
2) “Saturday Night Live,” 11:29 p.m.. NBC. After its triumphant Eddie Murphy episode, “SNL” has gone on a rerun binge. Here’s the fifth straight, this time with Jennifer Lopez hosting and DaBaby as music guest. There will finally be a new one next week, with Adam Driver and Halsey.
3) Boxing, 8 p.m. ET, Fox; and basketball, 8:30, ABC. These are forces unaccustomed to losing: A superwelterweight bout has Julian Williams and Jeison Rosario; combined, they have 46 wins, two losses and two ties. And an NBA game has the Lakers at the Rockets; at mid-week, they were 59-20.
4) “NCIS: Los Angeles,” 8 p.m., CBS. This rerun from last May has Callen getting a lead on the whereabouts of Anna Kolcheck, the spy/counterspy played by Bar Paly. Soon, he’s taking the team on an unsanctioned mission to Cuba.
5) “On the Basis of Sex” (2018), 9-11 p.m., Showtime. In August, Americans will mark the 100th anniversary of women’s right to vote; many other rights, however, are less than 50 years old. From 1973-75, young Ruth Bader Ginsburg argued six Supreme Court gender cases, winning five of them. Felicity Jones plays her appealingly, in a bracing and involving film.
