1) “Tenet” (2020), 8 p.m., HBO. Here’s the film that tried to revive moviegoing. Christoper Nolan (“Inception”) spent $200 million for a time-twisting science-fiction film starring John David Washington (shown here) aimed at big screens. Americans, however, weren’t ready to go back to theaters; it made only $58.5 million here and in Canada, doing better overseas. In the aftermath, other big-budget films were delayed or moved to streaming. “Tenet” did win an Oscar for its special effects and a nomination for its set design.
2) “NCIS: New Orleans,” 8 and 9 p.m., CBS. This show is wrapping up its seventh and final season on Sundays, with the finale on May 23. First, however, it reruns this two-parter, which takes a sharp look at the Navy’s treatment of sexual-assault complaints. The story begins with the murder of a therapist.
3) “The Masked Singer,” 9 p.m., Fox. Here’s a rerun of the “Maskie Awards” (which the show mis-punctuates as “Masky’s”). It repeats songs from the six remaining contestants and briefly glimpses the unmasked ones – Caitlyn Jenner, Danny Trejo, Logan Paul, Mark McGrath, Bobby Brown, Kermit the Frog … and host Nick Cannon, who slipped into a mask one week. Those seven combine for a closing song; there’s also a poignant moment as Brown mentions two of his children who died in their 20s.
4) More music. At 9 p.m., ABC reruns “American Idol,” with the top 12 singing songs that were nominated for Academy Awards. And at 11:29, “Saturday Night Live” reruns the episode with Nick Jonas doubling as host and music guest.
5) Also: It’s a strong movie night, led by “Tenet”; “Silver Linings Playbook” (2012), at 6:55 p.m. on Showtime; and “The Wizard of Oz” (1939), at 8 p.m. ET on Turner Classic Movies. Also: At 7 p.m. ET, Ovation wraps its two-part “Murdoch Mysteries” … which, alas, kicks the story to next season; at 8, NBC has the Inspiration Awards and BBC America continues “One Wild Day,” now visiting jungles.
