He is best remembered in the role of Ebenezer Scrooge in the 1951 film Scrooge, and for his portrayal of Miss Fritton, the headmistress in two St. Trinian's films. He was famously described by comedian Ronnie Corbett as a "sad-faced actor, with the voice of a fastidious ghoul", in Corbett's autobiography High Hopes.
