marriage
Sunday, 9pm, BBC One
It begins, as all great love stories do, with a married couple arguing over a jacket potato. Emma (Nicola Walker) and Ian (Sean Bean) continue to bicker on their flight back from Spain, then quietly make a drooling truce on the couch with a takeaway. Not much happens in Stefan Golaszewski’s new four-part drama, but that’s the point, really. Life after the holidays resumes: a recently fired Ian spends the day at the leisure center and supermarket, then his daughter takes her boyfriend out for tea. The plot may be deceptively simple, but it is brilliantly acted and delicately captures the minutiae of everyday ups and downs, interactions and well-versed chatter. Hollie Richardson
the princess
9pm, Sky Documentaries
What else can be said about Diana, Princess of Wales 25 years after her death? Yet this haunting documentary from the Oscar-winning team behind Man on Wire and Searching for Sugar Man lets more than 90 minutes of superbly curated footage do the talking. The shot of a “Don’t do it, Di!” The badge before their royal wedding speaks volumes. HR

8 p.m., ITV
Marc Warren’s grim detective is reluctantly thrown into the ruthless world of Amsterdam’s diamond trade when his latest murder case involves the heirs of a wealthy company. There’s also something of a steal, as Darrell D’Silva continues to steal scenes as the pizza-devouring pathologist Hendrik. Graeme Virtut
Afghanistan: Exit
9pm, BBC Two
Last August, the US finally withdrew its troops from Afghanistan after a 20-year war that was overseen by four different presidents. Barack Obama – and his attempts to repatriate American forces – is the focus of the first of a two-part documentary that tells the story of the war’s final throes. HR
A very British way of torture
10 p.m., Channel 4
Amid the current crop of films about colonial history, absent from the curriculum for many, here is one about Britain’s role in a war in Kenya against the Mau Mau, a movement that fought for independence against foreign rule, in the 1950s. Experts use new evidence to detail a shameful regime of systemic torture. HR
Walter Presents: Hide and seek
22.55, Channel 4
The first Ukrainian offering from Channel 4’s subtitled section is a familiar-sounding but compelling police procedural: two detectives with a troubled past investigate the disappearance of a little girl. Yuliya Abdel Fattakh is particularly good as Detective Varta, another disaffected Eastern European cousin of The Bridge’s Saga Norén. Ellen E Jones

The campaigns and characters of the AIDS activist group Act Up in Paris in the early 1990s make for an emotional and compelling drama in Robin Campillo’s 2017 film. Amid argumentative meetings about strategy and own disruptive public actions (often with fake blood), the heartbreaking stories of the mostly HIV-positive members fade away. It’s also a sweet love story, as new boy Nathan (Arnaud Valois) falls in love with sick but angry Sean (a terrifyingly insane Nahuel Pérez Biscayart). Simon Wardell
