Two Doors Down: Christmas Special

9pm, BBC Two

The Glaswegian sitcom exits the suburbs for this festive special. When coronavirus restrictions put a spanner in Colin and Cathy’s plans for a luxury Christmas holiday in Dubai, the neighbours end up in a luxury lodge in the Highlands instead, pushing each other to breaking point. While Ian (Jamie Quinn) has some good news to share with his boyfriend, Gordon (Kieran Hodgson), Cathy (Doon Mackichan) soon begins to feel attacked by Beth (Arabella Weir). Ammar Kalia

Deep Fakes: Can You Trust Your Eyes?

Royal Institution Christmas Lectures 2020

8pm, BBC Four

The annual scientific series kicks off with a fascinating offering from the geology professor Chris Jackson, who details the history of Earth’s climate change, as stored in the makeup of ancient fossils.

Bradley Walsh & Son: Breaking Dad – The Unseen Show

Billy Connolly: It’s Been a Pleasure

9.30pm, ITV

It is sad to think that such an irrepressible source of good humour as Connolly is winding down. But the Big Yin’s retirement (two years ago) saw the comic finally pass on the torch. Paul McCartney, Elton John and Whoopi Goldberg pay their respects in this funny, touching tribute. Phil Harrison

Inside Out (Pete Docter and Ronnie Del Carmen, 2015), 1.20pm, BBC One
One of the brightest jewels in the Pixar crown, this dazzlingly inventive comedy takes place inside the head of 11-year-old Riley (Kaitlin Dias), where five bickering embodiments of feelings control her actions: Fear, Anger, Disgust, Sadness and – thankfully – the ebullient Joy (Amy Poehler).
