Sound film "The Clue of the New Pin", a British Lion production using the sound-on-disc British Photophone system. In May, "Black Waters", a British and Dominions Film Corporation promoted as the first UK all-talker, received its initial trade screening; it had been shot completely in Hollywood with a Western Electric sound-on-film system. None of these pictures made much impact. The first successful European dramatic talkie was the all-British "Blackmail". Directed by twenty-nine-year-old Alfred Hitchcock, the movie had its London debut June 21, 1929. Originally shot as a silent, "Blackmail" was restaged to include dialogue sequences, along with a score and sound effects,

Through what is two intersecting monologues the play "Hitchcock & Herrmann" explores the relationship between these two geniuses and endeavours to explain in their own words why at the height of their creative talents they parted company and never worked together again. Interspersed throughout are examples of Herrmann's music - often taking the place for important dramatic points. The play was first performed in January, 2005 as a rehearsed reading at the 4MBS Performance Studio in Brisbane, Australia with Knijnenburg himself playing the part of Hitchcock and Yalin Ozucelik
