Mr. Proudfoot Shows a Light is a 1941 British World War II public information/propaganda short film, directed by Herbert Mason, produced by Edward Black for 20th Century Fox and featuring cameos from a number of well-known actors of the day. The film was commissioned by the Ministry of Information and was designed to emphasise, in a humorous manner, the need for absolute adherence to wartime blackout regulations. It includes some studio-bound footage of a Luftwaffe base and the interiors of plane cockpits, alongside genuine newsreel footage of an aerial dogfight and a downed plane.
