TV tonight: the first family in the world to be diagnosed with heriditary Alzheimer’s

The Jennings vs Alzheimer’s

9pm, BBC Two
If you were going to get dementia, would you want to know? Part terrifying, part hopeful, this documentary follows the children of Carol Jennings who, after her Alzheimer’s diagnosis in the 80s, lobbied for research into the disease being hereditary, which led to confirmation of a mutant gene. Charting what happened since, the film takes us to the question: are we in the Alzheimer’s treatment era? Hollie Richardson

Meet the Richardsons

Jon wants to buy a field while Lucy brandishes a quiche after a bottomless brunch in the latest episode of the mockumentary, made poignant by news of the pair’s split.

Film choice

Outland (Peter Hyams, 1981), 9pm, 5Action

Basically High Noon in space, Peter Hyams’s 1981 sci-fi thriller is one of the better films to come out in the wake of the groundbreaking Alien (that film’s composer, Jerry Goldsmith, contributes a similarly unnerving score here). Sean Connery is the last good man standing as the federal marshal of a mining colony on Jupiter’s moon Io. When he gets in the way of the (company-approved) illicit trade in performance-boosting amphetamines, hitmen are sent after him. Grimy and gripping. Simon Wardell
