Sound Test for Blackmail
1929 · Released · 1 min
Alfred Hitchcock makes an experiment in this short film where he uses the sound device for the first time in a motion picture of his own. This is a sound test where the master of suspense and actress Anny Ondra have some humored dialogues, just checking the sound quality designed for Hitchcock's first talkie picture, the classic Blackmail (1929).
