The hypnotic Svengali controls the singing voice of a young starlet, but he cannot control her heart. This 1915 Maurice Tourneur film is a version of the famous du Maurier novel. It was later done in a more famous 1931 film named Svengali with John Barrymore. The later film obviously changed the title due to the huge presence of its star.
