Miriam’s Dead Good Adventure
9pm, BBC Two
Look past the naff title and what you have here is the first of an excellent two-part film in which Miriam Margolyes embarks on a mission to confront her fear of ageing and death. She travels to hospices, homes for dementia patients, and laboratories dedicated to prolonging human life, then talks to the Californians making up the “super-longevity movement”. Unimpressed by the latest fads, she remains pragmatic, concluding: “It’s not the length of the life that matters, it’s the quality of every second.” Mike Bradley

Film choice
Saving Mr Banks 3.40pm, BBC One
The origins of the film legend that is Mary Poppins, served with a spoonful of sugar by director John Lee Hancock. Emma Thompson is the crotchety PL Travers, awfully protective author of the book that Tom Hanks’s Walt Disney is desperate to bring to cinematic life: it’s a supercali (etc) double act.
