Best TV shows on TV tonight

World on Fire season 2, 9 pm, BBC One

After succumbing to the pressures of leadership during the Siege of Tobruk, Lieutenant Harry Chase (Jonah Hauer-King) returns home to Manchester in tonight’s series finale. With Sir James swanning about the place and Kasia now working for MI5, many things have changed. 

She’s mellowed on some fronts, but when it comes to her son Robina remains as intransigent as ever. Harry’s desperate to find out more about his father, who took his own life after returning from the trenches of World War One, and a difficult scene between mother and son highlights the corrosive effect grief can have if left unchecked.

Rob’s duties include mastering a snow shovel before graduating to tractor-driving, followed by a splash of cold-water swimming. Meanwhile, Monica is mesmerisingly in her element in the kitchen before getting the resort’s trawler shipshape for guests. After a whale of a time, will they experience the Northern Lights?

Best film on TV tonight

The Power of the Dog, 10 pm, BBC Two

TV tonight Benedict Cumberbatch stars

In one of his most complex but complete performances, Benedict Cumberbatch towers over all in Jane Campion’s stunning Gothic western. It’s 1920s Montana, and a bullying, viper-like Cumberbatch runs a ranch along with meek brother Jesse Plemons, but finds new targets for his venom when Plemons introduces him to new wife Kirsten Dunst and her willowy son Kodi Smit-McPhee. 

A story of uneasy masculinity, repression, revenge and familial spite, but those toxic elements are counterbalanced by simply stunning vistas (New Zealand filling in for the US), in a film that proves Campion (The Piano, Portrait of a Lady) has lost none of her power to awe.
