TV tonight: Glenda Jackson battles dementia in a new thriller

Elizabeth Is Missing

9pm, BBC One

Glenda Jackson stars in this feature-length adaptation of Emma Healey’s bestselling 2014 novel about an elderly woman attempting to solve the mystery of her disappeared friend. Jackson plays Maud with a heartbreaking tenderness as her dementia worsens and her past experiences increasingly fuse with the present – especially the previous disappearance of her own sister. It is Jackson’s first TV role for 27 years and a welcome return to the small screen in this not-so-festive yet engrossing drama. Ammar Kalia

Alexander Payne’s grainy black-and-white odyssey has Will Forte’s thirtysomething son reluctantly agreeing to take his ailing dad (Bruce Dern) on a 750-mile fool’s errand to Lincoln, Nebraska to collect a bogus $1m lottery prize.
