Who Do You Think You Are?
9pm, BBC One
Oscar-winner Kate Winslet is slightly shortchanged by the editing of an interesting genealogical journey that makes her come across as more discombobulated than she clearly is. That said, who wouldn’t be thrown by an exploration of the rumoured Scandinavian ancestry on their mum’s side that reveals horrors and hardships endured by their ancestors? Happier news awaits on her father’s side, leading her to conclude: “It makes me feel as though I fit somewhere more, knowing all of this.” Mike Bradley

When Bridges Collapse: The Genoa Disaster
9pm, BBC Two
A year on from the catastrophe that was the disintegration of Genoa’s Morandi Bridge – 43 people died – this documentary provides great detail on why it may have happened, and how similar collapses may still occur. Worrying viewing. Jack Seale
Succession
9pm, Sky Atlantic
HBO’s agreeably acrid drama returns for a second outing. Heir apparent Kendall Roy has been rendered near-catatonic by last season’s gut punch of a finale, offering the chance for his grasping siblings to pursue their own designs on the family’s media empire. But is their fearsome father willing to give up his crown just yet? Gwilym Mumford
The Great Train Robbery: The Hidden Tapes
9pm, Channel 4
Fleshing out interview tapes recorded in 1978 by the author Piers Paul Read for his book The Train Robbers, Antony Barnett’s film brings to life the “folk heroes” who plotted the “crime of the century”. Marvel at how the robbery was planned – and how one man escaped arrest to live off the loot until his death in 2015. MB
Eaten By an Escalator: When Machines Bite Back
10pm, Channel 5
Not quite enough to induce “escalaphobia”, but still pretty scary, this catalogue of chaos involving people being caught in the teeth of erratic escalators will make you think twice before fooling about in transit. Watch as one man almost castrates himself, another loses half a leg and a child traps his hand. MB
Film choice
Double Indemnity (Billy Wilder, 1944), 1.30pm, TCM Movies
Fred MacMurray’s insurance guy Walter and Barbara Stanwyck’s icy beauty Phyllis plot to off her husband and collect the insurance, but Walter’s mentor Barton (Edward G Robinson) smells a rat. A trio of superb performances anchor Billy Wilder’s film noir; it crackles with greed, desire and sardonic wordplay. Paul Howlett
