1) “Saturday Night Live,” 11:29 p.m., NBC. Carey Mulligan makes her “SNL” debut as host, with Kid Cudi as music guest. Mulligan has her second Academy Award nomination (this time for “Promising Young Woman,” shown here), a decade after being nominated for “An Education.” And on April 25, she’ll be featured in the final episode of PBS’ “My Grandparents’ War” documentary series.
2) Basketball, 8:30 p.m. ET, ABC, with preview at 8. The college tournament has finally ended and the pros get their game back … including Saturday nights on ABC. This one has James Harden and the Brooklyn Nets hosting the Los Angeles Lakers, who have been hobbled by injuries to LeBron James and Anthony Davis, but added rebounding powerhouse Andre Drummond.
3) “Murdoch Mysteries,” 7 p.m. ET, Ovation. A Toronto estate has declared itself a separate nation. That won’t stop Murdoch from investigating a murder there.
4) “Law & Order: Special Victims Unit” and “Law & Order: Organized Crime,” 8 and 9 p.m., NBC. Here are quick reruns of Thursday’s episodes. First, a girl disappears near a building housing several sex-offenders. Then Stabler and Bell add two people to their unit and investigate a pair of seemingly unrelated crimes.
5) “Lust: A Seven Deadly Sins Story,” 8-10 p.m., Lifetime. When Lifetime set its deadly-sins project, we kind of knew it would start with lust, not sloth. Other movies vary sharply: “Hud” (1963, 8 p.m. ET, Turner Classic Movies) is beautifully acted, winning Oscars for Patricia Neal, Melvyn Douglas and the black-and-white cinematography, plus a nomination for Paul Newman. “The New Mutants” (2020, 8 p.m., HBO) sat on a shelf for two-and-a-half years, then did weak business during the pandemic.
