Ant Middleton & Rebel Wilson: Straight Talking
9pm, Sky One
Following his bromantic journey through Namibia with former One Direction member Liam Payne in 2019, SBS man Middleton continues his chatshow-cum-endurance format with the Pitch Perfect star Rebel Wilson. The pair touch down in Mexico for some buggy driving and deep-sea diving while taking in the sights. Middleton then puts his interrogation techniques to good use, talking to Wilson about her recent weight loss and her experiences of fame. Ammar Kalia

If your January is the dullest on record, gather your bubble and surrender to the joy of watching dogs having a blowdry.

Death in Paradise
9pm, BBC One
This week: an obstreperous professor has been poisoned, but hasn’t consumed any food or drink in which the arsenic could have been placed. DI Parker (Ralf Little) muses on that and learns to cook crab, all while slowly repeating each new clue back to his colleagues. It’s a tough job but someone’s got to do it. Jack Seale

Whisky Galore! (Alexander Mackendrick, 1949) 10pm, BBC Four
This unlikely tale of a cargo ship running aground in the Outer Hebrides, bequeathing its 50,000 cases of whisky to the grateful islanders, is based on a real wartime incident. In Alexander Mackendrick’s hands it becomes a sublime Ealing comedy as the canny folk of Todday run rings round the Home Guard. Paul Howlett
