1) Academy Awards, 8 p.m. ET Sunday, ABC. For the third straight year, the Oscars will go without a host … and might pay little attention to the songs. That can be disastrous: Humor and music are key, when many winners give dreary speeches (thanking agents and such) and many viewers haven’t seen the films. Nominated for best picture are “Promising Young Woman” (shown here with Carey Mulligan), “Mank,” “Minari,” “Nomadland,” “Trial of the Chicago 7,” “Judas and the Black Messiah,” “The Father” and “Sound of Metal.”
2) Earth Day shows, Thursday. The world’s two best-known environmentalists meet on PBS. “My generation has made a mess of things,” David Attenborough, 94, tells Greta Thunberg, 18. Now both get their say: “Greta Thunberg: A Year to Change the World” is 8-11 p.m. on PBS. And Attemborough? “The Year the Earth Changed” just arrived on Apple TV+; coming Thursday are “Life in Color” (Netflix), “A Perfect Planet” (8-10 p.m., Discovery) and a two-day marathon (BBC America).
3) More Earth Day. You can start early: Apple has added two more nature films; Discovery+ added three, with “Endangered” arriving Thursday. Also Thursday, National Geotraphic jumps in – “Kingdom of the Polar Bears” (8 p.m., Nat Geo Wild”) and the gorgeous, “Secrets of the Whales” (Disney+). Also Thursday: marathons of “Serengeti” (2-8 p.m., Discovery) and “North America” (6-11 p.m., Animal Planet), plus the new “2040” (8-10 p.m., CW) and “Cher & The Loneliest Elephant” (Paramount Plus).
4) “9-1-1” and “9-1-1: Lone Star” return, 8 and 9 p.m. today, Fox. After five-week breaks, both shows deal with horrific car accidents. In “9-1-1,” that was caused by a drunken driver; also, Maddie (Jennifer Love Hewitt) goes into labor, while the devastated Hen and Karen prepare their foster daughter to be reunited with her birth mother. And in “Lone Star,” one of the firefighters (Judd) is a crash victim; as he and his wife Grace (a 9-1-1 operator) linger near death, flashbacks show how they met and fell in love.
5) “Cruel Summer” debut, 9 and 10 p.m Tuesday, Freeform. Bouncing between three summers, we get sort of a triple role for young Chiara Aurelia. She’s Jeanette, a shy teen who has loving parents, two friends and a secret envy of beautiful Kate (Olivia Holt). A year later, Kate is missing and Jeanette has it all, including Kate’s boyfriend; a year after that, she’s widely hated. This might sound like a tacky soap, but it has a smart script and great performances – especially by Aurelia, 18, a virtual newcomer.
6) “Snowfall” season finale, 10 p.m. Wednesday, FX, rerunning at 11. Two events have propelled fierce collisions: A reporter (tipped by Franklin’s father) wrote about Teddy’s CIA guns-for-drugs scheme; also, Leon accidentally killed the young niece of Manboy, a rival gang boss. Last week, Teddy killed the reporter after a car crash; Franklin ambushed and killed Manboy and his gang. Now come the aftershocks, some quiet, some not. This feels like a great series finale, but “Snowfall” will return.
7) “Hell’s Kitchen” finale, 8 p.m. Thursday, Fox. Six straight times, this has had a female champion. Now that will be seven: Mary Lou Davis, 28, a chef de cuisine (kitchen manager) in San Antonio faces Kori Sutton, 37, an executive chef in Los Angeles. Both have chosen their teams from the previous contestants; each has to create a full menu and dinner service. The winner will become the head chef of Gordon Ramsay’s Lake Tahoe restaurant; if Sutton wins, she’ll become the show’s oldest champion.
8) “Great Performances: Romeo and Juliet,” 9 p.m. Friday, PBS. For the prestigious National Theatre in London, this was going to be a big event – Shakespeare’s classic, starring Josh O’Connor (Charles in “The Crown”) and Jessie Buckley (the killer nurse in the latest “Fargo”). Then came the pandemic and a bold decision: Skip the audience and film the show in the theater building, starting with minimal sets. The result, brilliantly directed and perfectly played , might even grip people who dislike Shakespeare.
9) Musicals, Saturday. It’s usually hard to find one good musical; here are three great ones on the same night. “Dreamgirls” (2006, 8 p.m., HBO) arrived a quarter-century after its Broadway debut; it drew an Oscar for Jennifer Hudson, a nomination for Eddie Muphy and great work from Beyonce, Jamie Foxx and more … “Bohemian Rhapsody” (2018, 8 p.m., FX) has Rami Malek’s Oscar-winning work as Freddie Mercury … “Moana” (6:50., Freeform) is an animated gem, with newcomer Auli’i Cravalho.
10) And comedies, CBS. The bad news is that “Mom” – sometimes TV’s best comedy – has only four shows left in its final season. The good? Producer Chuck Lorre has plenty more. The delightfully droll “Bob (Hearts) Abishola” is 8:30 p.m. Mondays; tonight, Kemi (the brilliant Gina Yashere, the show’s co-creator) is devastated by romance. On Thursday (competing with Earth Day shows, 8-10 p.m.) are “Young Sheldon,” “United States of Al,” “Mom” (a big project puts friends at odds) and “B Positive.”
