1) “Now Hear This” season-finale, 9 p.m., PBS. This is the show’s best hour yet, a visit to Iceland. The scenery is stunning (shown here in a generic view, not from the show), the people are appealing — “we’re doers,” one says — and the music is abundant. With only 400,000 people, Iceland averages 500 new albums a year. This hour ranges from choral music inside a volcano to a thundering cello concerto.
2) Kentucky Derby preview, 8 p.m., NBC. The race itself (6:57 p.m. ET Saturday) will be two minutes or so, but the previews are eternal. A one-hour one tonight will be followed by a marathon at 2:30 p.m. ET Saturday.
3) “Fire Country,” 9 p.m., CBS. Here’s a new sort of crisis: A storm sends a telephone pole crashing into a house, leaving a woman trapped. Also, at 8 p.m., “Sheriff Country” probes what’s said to be a hunting accident; at 10, “Boston Blue” sees a serial killer hint at knowing where a missing child is.
4) “Wuthering Heights” (2026), HBO Max. The 1847 novel had at least seven previous films, but never like this. Every character is unlikable, but director Emerald Fennell keeps us watching the steamy sex, stunning visuals and great cast, led by Margot Robbie, Jacob Elordi and Martin Clunes. It has its streaming debut today, then airs Saturday on HBO.
5) More movies. There are two classics — “Titanic” (1997) at 8 p.m. on VH1 and “To Kill a Mockingbird” (1962) at 8 ET on Turner Classic Movies. “Man on Fire” (2004) is 9 p.m. on Starz, one day after a mini-series remake debuted on Netflix. And the Acorn streamer launches “murder mystery May” with “The Limehouse Golem” (2016), a Victorian-era serial-killer tale.
