Men Up

9pm, BBC One

Wales’s finest, including Iwan Rheon and Joanna Page, tell the story of the first men to trial Viagra in Swansea in this brilliant feature-length drama. Set in 1994, it follows five very different men who are impotent – including a man who lies about being gay because the trial is for straight people, another who worries his wife thinks she is the problem after having a double mastectomy, and a widower who is afraid to meet up with his lonely hearts match for fear of being intimate again. It’s a fun, heartwarming watch from writer Matthew Barry and executive producer Russell T Davies – but perhaps one to swerve if sharing a box of Celebrations with the in-laws on the sofa.

Gardeners’ World Winter Specials

8pm, BBC Two

Frances Tophill visits Wildside gardens in Devon, where preparations for spring are keeping everyone busy. In Bedfordshire, Nick Bailey discovers a garden where grasses, trees and topiary combine to make the cold months look warm. And Advolly Richmond celebrates the greenhouse. JS

Would I Lie to You?

8.30pm, BBC One

Messrs Brydon, Mack and Mitchell could probably play their parts in their sleep by now in this evergreen panel show. Joining them are Rav Wilding, Alex Jones, Chris McCausland and the eccentric joker in the pack, Su Pollard. Phil Harrison

Mortimer & Whitehouse: Gone Hogmanay Fishing

9pm, BBC Two

This special strikes a perfect balance: hilarity rubs shoulders with the kind of emotional honesty that can only exist between two old friends who know each other’s foibles. Bob and Paul fish for salmon in the River Dee and are joined by two special guests to ponder times past and drink to absent friends. A delight. PH

Based on a True Story

9pm, Sky Max

Kaley Cuoco and Chris Messina are united as a down-on-their-luck married couple in this new series, which is part dark comedy thriller and part true-crime satire. When Ava and Nathan cross paths with a potential murderer (Tom Bateman), they start a podcast, of course. Ellen E Jones

The Kemps: All Gold

10pm, BBC Two

There a more laughs a minute here than any other Christmas comedy: Martin and Gary Kemp return in Rhys Thomas’s shamelessly silly mockumentary. Gary’s preparations for Spandau: The Ballet are interrupted when Martin is served divorce papers by Pepsi & Shirlie, and the brothers accidentally form a supergroup with Francis Rossi from Status Quo.

Film choices

Polite Society (Nida Manzoor, 2023), Sky Movies Premiere, 1,45pm and 8pm

Manzoor’s martial arts comedy is a colossal amount of fun; a whipsmart, genre-bending coming-of-age story about a British-Pakistani woman who dreams of becoming a stunt performer, largely because she wants to be like Eunice Huthard, the 1994 series champion of Gladiator. This week is quite heavy on martial arts films, but this is worth seeking out regardless. Stuart Heritage

Harry Brown (Daniel Barber, 2009), Disney+
At the time of its release, Harry Brown was positioned as a cousin to Get Carter, in that they both feature Michael Caine deciding to take justice into his own hands. In truth, this movie is really more of a Gran Torino, as it is about a man with a violent past who struggles to function in the world. Still, nice to have this version of Caine around. SH

Funny Girl (William Wyler, 1968), BBC Two, 4.05pm

Someone at the BBC has clocked that Barbra Streisand has a memoir out this Christmas, as it has devoted an entire afternoon to her. Presented in a double bill with 1969’s Hello, Dolly!, Funny Girl was Streisand’s first film, and still her finest hour. Charming and weird and heartbreaking in equal measure, Streisand essentially used Funny Girl to change the face of what a leading lady could be. SH

Game Night (John Francis Daley and Jonathan Goldstein, 2018), BBC One, 12.10 am and Sky Cinema Premiere, 8pm
Daley and Goldstein, who specialise in making films that are far better than they have any right to be, wrote and directed this ambitious comedy – a riotously silly riff on David Fincher’s The Game – about a group of people whose game night spills out of control and seeps into the criminal underworld. Everyone is on top form here: it is almost universally the best film that anyone in its cast (which includes Jason Bateman and Rachel McAdams) has ever been in. SH
