It’s called Elizabeth Is Missing, and its available on DVD and streaming on PBS Passport. Looking haggard at the age of 85, Jackson proves that her acting ability is in topnotch condition, even as her wrinkled face and scrawny physique show advanced age. She embodies the lead character of Maud Horsham, a woman who is sinking, or has sunk, into dementia. Elizabeth Is Missing is a UK production shot in Paisley, Scotland. Andrea Gibb wrote the screenplay, which is based on a novel by Emma Healey. Gibb has quite a resume, having penned episodes of PBS series Sanditon and Call the Midwife, as well as such humanist feature films as AfterLife about a journalist who cares for a sister with Downs Syndrome and Dear Frankie, the story of a mother who forges letters and hires a stranger to pose as her young son’s missing father.
