Blackmail is a 1929 British thriller drama film directed by Alfred Hitchcock and starring Anny Ondra, John Longden, and Cyril Ritchard. Based on the 1928 play of the same name by Charles Bennett, the film is about a London woman who is blackmailed after killing a man who tries to rape her. After starting production as a silent film, British International Pictures decided to adapt Blackmail into a separate sound film. It became the first successful European talkie; a silent version was released for theaters not equipped for sound (at 6,740 feet), with the sound version (7,136 feet) released at the same time. Both versions are held in the British Film Institute collection. Blackmail is frequently cited as the first British sound feature film. Voted the best British film of 1929 in a UK poll the year it was released. In 2017 a poll of 150 actors, directors, writers, producers and critics for Time Out magazine ranked Blackmail as the 59th best British film ever.

He gives her a dancer's outfit and Crewe sings and plays "Miss Up-to-Date" on the piano.

He attempts to rape her; her cries for help are not heard on the street below. In desperation, Alice grabs a nearby bread knife and kills him. She angrily tears a hole in the painting of the clown, then leaves after attempting to remove any evidence of her presence in the flat, but accidentally leaves her gloves behind. She walks the streets of London all night in a daze. When the body is found, Frank is assigned to the case and finds one of Alice's gloves. He also
