Have you ever heard the expression, "He's a real Svengali?" It refers to a man who holds way too much control over another person. This is the moviethat gave us that name. John Barrymore (Drew's grandfather) stars as the master manipulator who uses hypnosis to control the beguiling Trilby (Marian Marsh).At first, Svengali convinces Trilby she can become a great violinist, but soon he's got his hooks into her so deeply that she can't perform for anyone except him. That's just how he likes it, but Trilby's beau Billee (Bramwell Fletcher) might have something else to say about the matter.
