Donat and Asherson reprised their stage roles in the film version of "The Cure for Love" (1949). His only film as director, its production was affected by his ill health. The film's soundtrack had to be re-recorded after shooting was completed because Donat's asthma had severely affected his voice. Modestly received by a reviewer in "The Monthly Film Bulletin", and described as "pedestrian" by Philip French in 2009, it was a hit in the North. In this film, Donat used his natural Mancunian accent, which his early elocution lessons had attempted to suppress completely.
