TV tonight: a groundbreaking sketch show that delivers on the laughs

A Black Lady Sketch Show

9pm, Sky Comedy

There are a number of firsts attached to this smart sketch show: the first all-black-female writers’ room (led by Lauren Ashley Smith), the first black female sketch director (Dime Davis), and the first sketch series cast composed entirely of black women. It’s more than a museum piece, though – its creator, Robin Thede, creates an astutely observed comic environment, with tonight’s opening episode featuring an ode to the perils of ashy skin and a cameo from Angela Bassett.

War on Plastic: The Fight Goes On

9pm, BBC One

One year on from their first War on Plastic series, the battles continue to rage. In this special, Hugh Fearnley-Whittingstall and Anita Rani set their sights on fast food chains still giving away plastic toys, as well as questioning the environmental impact of disposable face masks. AK

Sheridan Smith: Becoming Mum

9pm, ITV

The actor and singer allows cameras into her home, following her to scans and therapy appointments as she prepares to give birth to her first child. It’s all in aid of a good cause: spreading awareness around the mental health struggles that one in three pregnant women experience. Ellen E Jones

Call the Cops

9pm, Channel 4

With new threats and dwindling resources, the police’s lot is not a happy one. This fly-on-the-wall series follows units in Devon and Cornwall, and delves into the heart of their control rooms, where officers must prioritise cases. As ruefully observed here, it’s a task akin to “juggling chainsaws while being on fire”. Ali Catterall

All Creatures Great and Small

9pm, Channel 5

This well-crafted adaptation of the cherished James Herriot canon offers a welcome time-warp to 1930s Yorkshire. Newcomer Nicholas Ralph is the eager young vet apprenticed to oddball Siegfried (Samuel West). As in the 1978 series, Tristan doesn’t turn up until episode two. Graeme Virtue

Skin

10.45pm, BBC One

Turns out it’s not all skin deep in this new dermatology-themed series, available in full on BBC Three. A specialist clinic opens its doors to young people affected by unusual skin conditions, tonight featuring Chantelle, who confronts her acne, while Amy asks if her facial birthmark could be lightened.

Film

Thelma and Louise 9pm, 5Star
The Ridley Scott road movie that found a new gear, putting two devil-may-care women in the driving seat as waitress Susan Sarandon and abused wife Geena Davis head off on a weekend jaunt that quickly swerves out of control with the death of a rapist. The tone remains upbeat, but they’re on a road to nowhere. Paul Howlett
