Hitchcock's silent Blackmail is one of the best British films, if not the best, of the late 1920s. Made in 1929, during the transition to the sound era, it was commissioned as part-silent and a part-talkie with music and some dialogue scenes. Czech film actress Anny Ondra stars as Alice White, a young woman whose brief flirtation with an artist turns suddenly and terribly sour. Hitchcock's masterly thriller boasts great London locations including the British Museum, Whitehall and the Lyons Tea House at Piccadilly Circus.
