David Attenborough is bringing it home for what is reportedly going to be his final series filmed on location. Over five beautiful episodes, the 96-year-old shows off the natural riches of the British Isles and the role they play in the survival of species across the world. He kicks things off with some big players: killer whales patrol the kelpy waters off Muckle Flugga; golden eagles breed in the Caledonian forest (which is now only 1% of its original size); and – bringing the drama – beloved puffins go head to head with the cunning black-headed gull over an eel lunch on the Farne Islands. It’s a wonderfully on-brand final bow for the nation’s favourite naturalist. Hollie Richardson
There’s an appropriately funereal mood for this last ever episode, as the cryptic crossword-loving Morse (Shaun Evans) investigates a number of unusual death notices in the Oxford Mail, leading him to a local undertaker’s and some moody reflections on mortality. But take heart: every end is a new beginning, and that’s particularly true of prequels. Stick around for a special documentary, Morse and the Last Endeavour, at 10.20pm. Ellen E Jones

The deft 80s-set thriller reaches its penultimate episode, and all those involved in the Brink’s-Mat blag are feeling the squeeze, even slick lawyer Cooper. As the taskforce tightens its net, there is a crash course in walkie-talkie etiquette from Jennings, while boss man Boyce hightails it to Zurich to take on Swiss banking privacy laws. Graeme Virtue
We Need to Talk About Cosby

Oscars 2023: The 95th Annual Academy Awards
midnight, Sky Arts
To the Dolby Theatre in LA, where the 95th Academy Awards features a fairly open race for the big prizes: late momentum behind Everything Everywhere All at Once has made it an apparent lock for best picture, but the major acting gongs are closely contested. Jack Seale
To Leslie, 5.55pm, 2.50am, Sky Cinema Premiere
The controversy over the (successful) campaign to get the film’s star, Andrea Riseborough, an Oscar nomination has taken away from what should be universal praise for her lacerating performance. In Michael Morris’s touching drama of redemption, she plays self-destructive alcoholic Leslie who, after frittering away a $190,000 lottery win, finds herself homeless. Hoping to reconnect with the teenage son she abandoned, she falters and fails, but then meets Marc Maron’s motel manager Sweeney. He seems like a soft touch but his gentle persistence offers her a way out of her cycle of harm. It’s not as hard-edged as it could have been, but in Riseborough’s hands it’s utterly compelling.

The Third Man, 2.40pm, BBC Two
Carol Reed’s riveting 1949 thriller reunites Orson Welles with his Citizen Kane co-star Joseph Cotten in a ripped-from-the-headlines tale of black marketeers in bombed-out postwar Vienna. It features one of the most distinctive cameos in cinema from Welles, but it’s really Cotten’s film. His pulp fiction author Holly Martins finds himself in one of his wild west plots when he arrives in the city to discover his old friend, Harry Lime, has just died. Alida Valli adds heart as Lime’s actor lover but it’s a bracingly cynical drama, all askew angles and subterranean intrigue. SW
