Ken Russell's composer biographies hit their apex with his stylized take on Tchaikovsky in "The Music Lovers." Three years later, Russell began his descent with "Mahler." Structured as a series of flashbacks, it may be hard to follow for anyone unfamiliar with the events and chronology of Mahler's life. The conversion sequence sets a new standard for poor taste, even for Russell. Robert Powell gives a fine performance, aided by a close resemblance to the real deal. Georgina Hale failed to make an impression in her appearance in Russell's "The Boy Friend," and is tentative, at best, here in a leading role as wife Alma. Antonia Ellis, another alumna of "The Boy Friend" is game for anything Russell throws at her. Even with a taste for the Russell treatment, "Mahler" may be a little hard to swallow.
