On TV tonight: The brilliant Anna Maxwell Martin stars in Until I Kill You | television and radio

Until I kill you

Sunday, 9pm, ITV1

Anna Maxwell Martin is at her most compelling in this four-part true crime drama from Nick Stevens (In Plain Sight, The Pembrokeshire Murders). It tells the story of Delia Balmer, a nurse and slightly prickly loner. When she ends her relationship with John Sweeney (Shaun Evans) – in which he almost strangled her – he admits to killing his ex, then ties Delia to a bed for four days before attacking her with an axe. The real Delia, who also wrote a book about her experiences, worked on the script with Stevens, who says he wanted to explore what happens when “someone who is not an easy victim finds themselves in a situation [the UK’s] Legal system”. A fascinating watch. Holly Richardson

Asia

6.20pm, BBC One

David Attenborough is still at it and this time he's narrating a beautiful new seven-part series about the natural world of Asia. It begins “beneath the waves” in the waters home to 60% of all marine life – including tree-climbing fish, a juvenile sperm whale and glow-in-the-dark squid. Human Resources

Show trial

9pm, BBC One

Justin (Michael Socha) finally takes a stand in his murder trial – and he's not the only one who's stuck with it for the rest of his life. Sam (Adeel Akhtar) has been given a new prescription for suicidal thoughts and Felix is ​​itching for excitement. But is “mental health” a defense against the killing of a person and possibly the planet? The jury is still out. Ellen E. Jones

Mortimer & Whitehouse: Gone Fishing

9pm, BBC Two

More heart-touching tales from the riverside as Bob, Paul and Ted the terrier attempt to catch a large rudd from a lake near Epping Forest. With a chill in the air and nervous geese on the water, the wait can be a long one. But if Paul is thinking about saying a prayer for a bite, Bob has booked the perfect place to stay. Graeme Virtue

Generation Z

9pm, Channel 4

The darkly comic zombie horror continues as snarky pensioner Cecily (the fabulous Sue Johnston) performs backflips to lure new recruits to her monstrous ways. As the nursing home rages, Finn runs afoul of the authorities and Kelly has family problems. All that and the danger of being eaten at any moment. Hannah Verdier

Dwarf story: life without little people

10.15pm, ITV1

A complex documentary about three people who tested a new drug to treat the most common cause of dwarfism – achondroplasia. But should dwarfism even be considered something that needs to be “cured”? We hear their experiences. Human Resources

Film selection

Sasquatch Sunset, 10:10 a.m., 10 p.m., Sky Cinema Premiere

This strange story is reminiscent of the old Disney nature films, in which an animal was followed for over a year and wildly anthropomorphized. But in Nathan and David Zellner's version, the subject is Bigfoot. In the remote forests of North America, a hairy, grunting Sasquatch family (two of which are inexplicably played by Riley Keough and Jesse Eisenberg) eat leaves, have sex, sniff skunks and make unsuccessful attempts to find more of their own kind. It's often funny, but there's an unexpected pathos in her fragile life. Simon Wardell
