1) Academy Awards, 8 p.m. ET, ABC. The bad years – with no host, no music and little fun – are apparently behind us now. This will have three hosts — comedians Amy Schumer and Wanda Sykes and actress Regina Hall. The best-song nominees, exiled to the pre-show last year, will be performed by Beyonce (shown here), Billie Eilish, Reba McEntire and Sebastian Yatra. And eight of the 23 categories will be handled before the telecast, leaving more time for entertainment.
2) Oscar previews. Red-carpet coverage starts at 6:30 p.m. on ABC and 5 p.m. on E – which also has “Brunch at the Oscars” at 2 p.m. and an “After Party” at 11. Also, “Dune” (a best-picture nominee) is at 6:15 p.m. on HBO, overlapping with the Oscars. And the Oscar marathon on Turner Classic Movies includes “An American in Paris” (1951) art 2 p.m. and “Gone With the Wind” (1939) from 4-8 p.m.
3) Basketball, 2 and 4:30 p.m., CBS. It’s time to round out the college tournament’s final four. Two teams advanced Saturday, with the other two today. They’ll collide Saturday in New Orleans.
4) “Killing Eve,” 8 p.m., BBC America. Flashbacks trace Carolyn, Konstantin and the birth of The Twelve, alongside some varied moments from nowadays. A murder scene is extremely unlikely; the final scene packs a fierce jolt. If you’re busy with the Oscars, you can catch this Monday on AMC.
5) ALSO: There’s another terrific “Sanditon,” this time with Charlotte working a nanny for the daughter and niece of a sullen widower. That’s at 9 p.m. on PBS, following another surprisingly dark “Call the Midwife” at 8. And even on Oscar night, cable is stuffed with new episodes at 9. That includes “The Walking Dead” (AMC), “Outlander” (Starz), “Winning Time” (HBO) and “Billions” (Showtime).
