Gaslight (released in the United States as Angel Street) is a 1940 British psychological thriller directed by Thorold Dickinson starring Anton Walbrook and Diana Wynyard, and features Frank Pettingell. The film adheres more closely to the original play upon which it is based – Patrick Hamilton's Gas Light (1938) – than does the 1944 MGM remake. The play had been performed on Broadway as Angel Street, so when the MGM remake was released in the United States, it was given the same title as the American production.
