The Fatal Night is a 1948 British thriller film directed by Mario Zampi and starring Lester Ferguson, Jean Short and Leslie Armstrong. It is based Michael Arlen's 1925 short story The Gentleman from America, which tells the story of an American visitor in London who makes a bet with two Englishmen to see if he can spend a night alone in a "haunted" room. The story was adapted for the screen by British crime novelist Gerald Butler. The same story, under its original title, was adapted in 1956 as an episode of the television series Alfred Hitchcock Presents.
