Glenda Jackson makes her return to screen acting after 27 years. During that time she became an elected Labour MP and Minister of State for Transport.
It is easy to dismiss this as a drama of an old woman with advancing dementia. Elizabeth is Missing shares somewhat with Christopher Nolan's Memento. Maud is suffering from dementia. The missing memories means she has no idea as to what has happened to her friend Elizabeth.
Maud's search for Elizabeth also unlocks deeply buried memories of another mystery in Maud's past. That of her older sister who has been missing since 1949.
As the drama goes on, I sort of guessed what may have happened to Elizabeth. Maud's behaviour such as her constant gardening leads to a more interesting story.
Jackson claims that she understood the devastation of dementia from the old people's homes she visited during her time as a politician. You can tell you are watching a master craftsman at work, just watch her gait as Maud goes searching for her friend.
