About High Treason

High Treason is a 1929 British film based on a play by Noel Pemberton Billing. It was directed by Maurice Elvey, and stars James Carew, Humberstone Wright, Benita Hume, Henry Vibart, Hayford Hobbs, Irene Rooke, and Jameson Thomas. Raymond Massey makes his first screen appearance in a small role. The film was initially produced as a silent but mid-way during production, Elvey was pushed by the studio to add sound to the film in order to cash in on the talkies. The sound version was prepared in collaboration with Tiffany Pictures and this version was copyrighted by them in 1930 in the United States and never renewed making the sound version public domain in the United States. Tiffany Pictures used the sound-on-film RCA Photophone process to record the soundtrack. The film was also issued on sound-on-disc format using Tiffany-Tone (Vitaphone-type) sound discs. Although a third of the film was filmed in sound, Elvey maintained much of the silent footage and dubbed over the dialogue for shots that were originally silent, with Elvey himself voicing some of the minor characters, which he admitted when interviewed by the Manitoba Free Press shortly after the film was released in the US. Likewise, BIP's Blackmail, directed by Alfred Hitchcock, was also turned into a sound picture mid-way during production and many of the silent scenes used dubbed dialogue and sound effects in a similar fashion to High Treason.
