Towards Zero
9pm, BBC One
Challengers meets Agatha Christie in the latest slick adaptation, which follows the aftermath of the scandal of adulterous pro tennis player Nevile Strange (Oliver Jackson-Cohen) – who holidays at his coastal family pile with his wife and ex-wife. At Gull’s Point, owned by the no-nonsense Lady Tressilian (Anjelica Huston), there are more guests and residents with grudges. Naturally, a murder is ahead. Hollie Richardson
The Americas
6.45pm, BBC One
Made by the BBC for US broadcaster NBC over a five-year period, this epic nature series may have a wide double-continent scope, but its images are suitably stunning. Tom Hanks narrates as the Atlantic coast delivers swimming horses, swarming cicadas and, to finish, a celebration of trees. Jack Seale
The Bay
9pm, ITV1
A return for the Morecambe-set crime drama after nearly two years – and a return, too, for DS Jenn Townsend (Marsha Thomason), heading back to work after coping with her father’s death. She and the MIU team investigate the docklands murder of university student Hannah Dawson, amid tensions in the student community. Ali Catterall
St David’s Day: Calan in Concert
9pm, BBC Four

David Frost Vs
9pm, Sky Documentaries
It’s always great to see Muhammad Ali – “The Greatest” – in action, but was Frost a worthy opponent? The British chatshow host had presidents and pop stars against the ropes, while Ali seems only amused. At one point he says to Frost, with a sidelong smile: “You know what I mean … You’re not as dumb as you look.” Ellen E Jones
Oscars Live
10.30pm, ITV1
It’s perhaps not a vintage year, but it has certainly got tongues wagging. Emilia Pérez has a record number of nominations, but it comes with controversies. Conclave could take a surprise win after sweeping up at the Baftas and Sags. And, after both winning awards this season, either Demi Moore or Mikey Madison will surely take the lead actress gong. Conan O’Brien hosts. HR

Black Dog (Guan Hu, 2024), 6.50am, 2.15pm, Sky Cinema Premiere
A winner at Cannes last year, Guan Hu’s tender, downbeat drama is set in a sand-covered, post-industrial Gobi desert town in China on the eve of the 2008 Beijing Olympics. Paroled prisoner Lang (Eddie Peng) is hired to round up the area’s many stray dogs to prettify the place, but his sensitive personality leads him to hide one spirited canine in his own home. There’s some great doggy acting – and the monosyllabic Peng is pretty good too – as the duo realise they are kindred spirits. Despite the grim setting, it’s a surprisingly light-hearted drama. SW
The Wicked Lady (Leslie Arliss, 1945), 6pm, Talking Pictures TV
With its upper-class romance, lavish dresses and heaving bodices, Leslie Arliss’s 1945 period melodrama is typical of Gainsborough studios’ populist output. This is one of its best efforts, with Margaret Lockwood having a ball as the selfish, scheming Barbara (“always one for excitement”), who steals the dull but rich fiance of her best friend (Patricia Roc) then turns her hand to highway robbery. There, she joins forces with bad boy Captain Jack (a lubricious James Mason) and things go even further downhill. SW
Lynn + Lucy (Fyzal Boulifa, 2019), 11.55pm, BBC Two
Childhood friends Lynn (Roxanne Scrimshaw) and Lucy (Nichola Burley) are still close as grownups. They live opposite each other, and the former, who had her daughter when she was a teen, is godmother to the latter’s newborn son. But when the baby dies suddenly, and Lucy’s partner is arrested, the bond between them is stretched to breaking point. Fyzal Boulifa’s debut feature is a sharply observed tale of lies and judgment, in which moral certainties are hard to come by and social pressures can twist relationships, with the two leads giving performances of subtlety and emotional range.
