1) “A Wild Year on Earth” (shown here), 8 p.m., BBC America. This is what BBC does magnificently – gorgeous wildlife scenes, weaved together with a grand score. The six parts will cover two months at a time. That starts with a few creatures – great horned owls (beautifully filmed) and polar bears — that are comfy in the frozen North. We also learn odd facts: Otters have nature’s thickest hair; manatees, by comparison, need warmth because (despite appearances) they lack blubber.
2) “Saturday Night Live,” 11:29 p.m., NBC. Three days after he performed at the inaugural party, we see Bruce Springsteen as the music guest. It’s a repeat – Timothee Chalamet hosts – wrapping up a string of five straight reruns; next week, “SNL” is back to new episodes.
3) “Salt-N-Pepa,” 8 p.m., Lifetime. Back in 1985, two Sears co-workersw (both nursing students) made a rap record that caught on. That “marked the beginning of a new era in hip hop,” Mimi Valdes wrote in “The Vibe History of Hip Hop.” Adding a 15-year-old DJ, they even performed on cafeteria lunch tables. Nelson George, a rap historian, says they created a “clean-cut sexuality,” in the Supremes mold. They sold 15 million records; their story is dramatized here.
4) “9-1-1” and “9-1-1: Lone Star,” 8 and 9 p.m., Fox. If you missed the season-openers on Monday, here are quick reruns. They’re filled with crises in California (the Hollywood reservoir breaks) and Texas (a tank rumbles through downtown Austin).
5) “Star Wars” marathon, all day, TNT. The films are re-arranged here to tell the story chronologically. “Pnantom Menace” (1999) is 6 a.m., with “Attack of the Clones” (2002) at 9 and “Revenge of the Sith” (2005) at 12:09 p.m. Then the original films air at 3:17 p.m. (1977), 6:09 (1980) and 8:52 (1983). Then the day’s first two films rerun at 11:52 p.m. and 2:53 a.m. There will be more on Sunday.
