Inspector Montalbano
9pm, BBC4
Luca Zingaretti’s Italian detective Salvo is back for another season of Sicilian sleuthing and heading back to Vigàta, much to the eternal chagrin of his long-distance missus Livia. This week, it’s the case of a 70-year-old prostitute strangled in her flat. Respected in town, she was sitting on a fortune, too. BBC4 can continue to try to persuade itself and others that this show is highbrow because it’s European, but Italo-Bergerac remains daft as a brush. Ben Arnold
Len Goodman’s Partners in Rhyme
6.45pm, BBC1
Sure as bourbons is bourbons, there will always be a place for friendly TV in the bland but comforting image of Blankety Blank and The Generation Game. This new panel show, hosted by Strictly’s Len Goodman, sees minor-league celebs and regular folks guess the answers to rhyming clues. Bafflingly 80s – as if irony, postmodernism and subtlety have nipped off and left uncle Len in charge – the result is compellingly terrible. Sophie Harris
Welcome to Edinburgh
7.30pm, BBC2
This introduction to the Edinburgh festival, presented by Kirsty Wark, is also a look back at the history of the event, which celebrates its 70th anniversary this year. Among the attractions profiled are Anoushka Shankar – who has taken up the family trade of sitar-playing, to much acclaim – and the National Theatre of Scotland’s new double bill Eve/Adam, a multimedia examination of the challenges faced by transgender people.

Iolo’s Great Welsh Parks
8pm, BBC2
Lantern-jawed, taciturn naturalist Iolo Williams heads for Margam Country Park on the edge of Port Talbot. He doesn’t linger longer on the history than politeness demands, instead going in search of the fauna. There’s plenty to be seen, including Père David’s deer – originally from China – and 11 species of bats, as well as some “very odd” water stick-insects. Williams, though, seems happiest observing coal tits (“Cracking little birds!” he exclaims). Jonathan Wright
Child Genius: The Final
8pm, Channel 4
“Winning is important, and there’s no shame in saying that.” So claims the positive, if anxious, father of one of the five bright young sparks who must score highly in both their niche subject areas and the quickfire buzzer round of the head-to-head to lift the coveted Child Genius trophy. It’s a tense watch that raises the issue of parental pushiness, but these children genuinely seem to relish the high-stakes, high-pressure rivalry. Sharon O’Connell
Outsider
10.30pm, Viceland
In 1987, martial arts master YK Kim self-financed an action movie about a rock band – made up of taekwondo experts – who take on a ruthless gang of ninja biker drug dealers. The result, Miami Connection, almost bankrupted him, was laughed out of every studio and almost ruined his life. More interesting than the film’s story is the wildly eccentric Kim’s, though both could do with a little more exploration than this new half-hour doc on so-bad-they’re-cult films allows. Luke Holland
Explorer
12midnight, National Geographic
“The internet provides some of the greatest gifts of our time; it has also become a weapon of mass destruction.” A timely comment there from veteran US newsman Ted Koppel, chatting with host Aasif Mandvi about Trump, fake news and edutainment, on tonight’s episode of the zippy US current affairs strand. Elsewhere: a look at grills (the oral, decorative kind), and the brutal war on drugs in the Philippines. Ali Catterall

The Lady in the Van (Nicholas Hytner, 2015) 9pm, BBC2
Maggie Smith is a marvel as Miss Shepherd, the eccentric old woman who parked her campervan in Alan Bennett’s drive and stayed for 15 years. Alex Jennings is a lugubrious joy as Bennett, but this is Smith’s film, her comically cantankerous exterior masking aching inner sadness. There’s fun, too, in the well-to-do neighbours’ reactions to her smelly presence. Paul Howlett
The Hunger Games: Catching Fire (Francis Lawrence, 2013) 9pm, Channel 4
Katniss Everdeen (the amazing Jennifer Lawrence) thought she’d finished with the gladiatorial Hunger Games, having survived everything the first film could throw at her. But devious President Snow (Donald Sutherland) has recognised her new, dangerously iconic status and forces her into a battle of the champions. An overlong sequel that nevertheless sets up the concluding Mockingjay episodes nicely. PH
Submarine (Richard Ayoade, 2010) 2.10am, Film4
Hard to resist this sweet-natured romcom from Richard Ayoade, AKA Maurice Moss of The IT Crowd. It’s the story of 15-year-old Oliver Tate (Craig Roberts), who is determined to lose his virginity before he hits 16 (preferably with Yasmin Paige’s Jordana) and to protect his mother (Sally Hawkins) from the seductive powers of old mullet-headed flame Graham (Paddy Considine). There’s real warmth and comedy in these characters. PH
