Interference (film)  Interference is a 1928 American drama film directed by Lothar Mendes and starring Clive Brook, William Powell, Evelyn Brent, and Doris Kenyon, all making their sound film debuts. In England when a first husband turns out not to be dead, blackmail leads to murder. The film was originally produced as a silent which was directed by Lothar Mendes. However, after its completion, Paramount halted it release and decided to remake the film completely in sound. The sound version was directed by special effects technician-turned-director Roy J. Pomeroy, as the basis for Paramount Pictures' first feature-length all-talking motion picture. Since Pomeroy lacked experience as a director, he was assisted by William deMille during the filming. It was based on the 1927 West End play "Interference" by Roland Pertwee and Harold Dearden. It was shot on a budget of $250,000 A silent version was also released to cater for theaters that had not yet wired for sound. While the sound version survives, the silent version is now lost. In 1935 it was remade by Paramount as "Without Regret". At a Remembrance Day service in London, Faith Marlay spots her former lover Philip Voaze who was supposedly killed during World War I. She discovers that he has actually survived the fighting and has been living under an assumed identity. Aware that his wife Deborah is now remarried to Sir John Marlay, a famous politician, she begins to try and blackmail Deborah by threatening to reveal her inadvertent bigamy. The film was praised in the "New York Times" as "a specimen of the strides made by the talking picture". However, a "Variety" review was more negative, describing "Interference" as "indifferent entertainment". At the London premiere, Clive Brook's mother remembered a gaff during the screening that put the crowd in an uproar. In one scene, Brook receives a postcard, tears it up and says, "Another one of those damn postcards." The needle on the disk for sound got stuck and kept repeating, "Another one of those damn postcards," over and over again while Brook, on-screen, took his wife into his arms and kissed her.
