Andy Serkis’s directorial debut is the true story of Robin and Diana Cavendish—when Robin contracted polio in 1957 the couple, with the help of a mad scientist friend, invented a wheelchair-based respirator. They brought it to market, eventually freeing thousands of polio sufferers from the inhuman confines of the iron lung. Yes, it’s a little disease-of-the-month-ish, but a treat for fans of Andrew Garfield. Note: the Japanese distributors have for some odd reason chosen to (miss)spell the title “Breath,” which is doubly confusing since another movie, also made in 2017, also bears that name. Grumble.
