 He worked in films throughout most of his career, and played more than sixty cinema roles.
 From an artistic but not theatrical background, Richardson had had no thought of a stage career until a production of "Hamlet" in Brighton inspired him to become an actor.
 He learned his craft in the 1920s with a touring company and later the Birmingham Repertory Theatre.
 In 1931 he joined the Old Vic, playing mostly Shakespearean roles.
