Escape to Costa Rica
7pm, Channel 4
In the first in this new series, environmental journalist Gaia Vince explores Costa Rica, home to more than 500,000 species of animal and currently the most sustainable country in the world. It should be completely carbon neutral by 2021, thanks to its national grid being sustained by natural resources such as rivers and volcanoes. Vince meets the president and also joins scientists who are helping to preserve the country’s forests. Ben Arnold
World’s Most Expensive Cars
4.30pm, Channel 4
Debut of a new series in which Ant Anstead follows the specialists of Sotheby’s as they search for collectible vehicles to auction. In this episode, they assess a garageful of glorious antiques in Italy and contemplate a super-rare convertible in Las Vegas: the very first Shelby Cobra, which might be worth as much as $10m. But the price tags are much less interesting than the stories behind the cars: happily, these are well told. Andrew Mueller
The Durrells
8pm, ITV
This week on the cracking comedy disguised as a gentle period sunshine drama, Larry (Josh O’Connor) is pretentiously outraged when nobody cares about his new novel. Dealing with her son’s dismay – a nice, sly satire on solipsistic creatives - is one of the spinning plates for chaos-parent Louisa (Keeley Hawes), who also has to deal with children not knowing their times tables and everyone getting smashed on homemade kumquat liqueur. Terrific fun. Jack Seale
Line of Duty
9pm, BBC1
As we left Ted Hastings last week, a long shadow had been cast over his probity. So in addition to catching a killer who knows how not to be caught, this finale involves considerably raised stakes in terms of AC-12’s future. What results is another hour of fist-bitingly intense drama and an ending that is simultaneously more conclusive and more ambiguous than you might expect. Think you know where this is going? Prepare to be confounded. Phil Harrison
Grantchester
9pm, ITV
The extremely watchable 1950s crime drama opens with a village cricket match, where the gentle competition is disturbed by racial tension. But that’s nothing compared to the tragedy that follows when the team are poisoned by the post-match beer and buffet. One resident is killed and it’s up to Sidney and Geordie to find out who’s responsible. Outside work, both chums’ entanglements with married women have the potential to cause scandal. Hannah Verdier
Genius
9pm, National Geographic
Continuing the biopic of one of history’s deepest thinkers. Geoffrey Rush’s tongue-out era Einstein is still some way off, so Johnny Flynn continues to portray young Albert in the vein of a steam-age Mr Robot. At Zurich Polytechnic, Einstein’s infatuation with Mileva Marić grows, despite the presence of a fiancee back home. With their affair threatening to extinguish the Bunsen on their academic studies, Professor Weber threatens to intervene. Mark Gibbings-Jones
100 Days of Trump
10pm, Viceland
The Vice squad attempt to find 100 stories from the first 100 days of the Mandarin Candidate’s reign – bans, regressive legislation, flip-flops – to illustrate his unique qualities and approach. This shouldn’t be difficult, given that the administration resembles a life-size representation of Hieronymus Bosch’s The Last Judgment, with designated zones of horror and damnation. If we’re lucky, there may even be another 100 days. Ali Catterall
Film choice
On Her Majesty’s Secret Service, (Peter Hunt, 1969), 4pm, ITV
Sean Connery is replaced by the one it’s always hard to remember, George Lazenby, in a Bond movie that has deservedly grown in estimation over the years. Blofeld is again the villain, now played by Telly Savalas, and director Hunt handles the snowy Alpine action well. The dark tone of Ian Fleming’s novel, heaping pain on his hero, survives as 007 meets his match in Tracy (Diana Rigg) and proposes marriage, a very risky undertaking. Paul Howlett
As Good As It Gets, (James L Brooks, 1997), 9pm, Sony Movie Channel
Jack Nicholson and Helen Hunt won Oscars for this, though their relationship in Brooks’s expensive-looking romcom is barely credible. He’s a fastidious, phobically challenged, irascible old writer; she’s a waitress at the one restaurant in town that still serves him, and there’s a sickly subplot concerning her ailing son. But it’s all done with consummate skill. Paul Howlett
Drive, (Nicolas Winding Refn, 2011), 11pm, BBC2
One of Ryan Gosling’s star-making roles: in Refn’s cool and highly stylised thriller, he plays a nameless getaway driver whose angelic features mask a capacity for extreme violence. He’s motoring along smoothly until his (sweetly platonic) involvement with neighbour Carey Mulligan gets him fatally mixed up with LA mobsters Albert Brooks and Ron Perlman. Paul Howlett
