David Cronenberg isn't credited often enough for his literacy, which anchors him as a filmmaker much as Method acting can anchor some performers: he seems to immerse himself so deeply in the warped visions of certain writers that he re-creates their work whereas most literary filmmakers would simply imitate it. This tour de force, which Patrick McGrath adapted from his own novel under Cronenberg's supervision, draws us into the consciousness of a schizophrenic (Ralph Fiennes) who's been incarcerated for most of his life and whose boyhood traumas merge seamlessly with his current existence in an east London halfway house; apparently Cronenberg's model is not only McGrath but Samuel Beckett in his early novels. The film asks us to piece together what really happened in the past, and even after two viewings I haven't entirely succeeded, but I was floored by Cronenberg's mastery of the material. Fiennes gives one of his finest performances; Miranda Richardson, playing at least three characters in the protagonist's twisted vision, is no less impressive; and Gabriel Byrne, Lynn Redgrave, and John Neville do excellent backup work. A lean and densely packed 98 minutes, this minimalist chamber thriller is at once hallucinatory and terrifyingly real. Music Box, Friday through Thursday, March 14 through 20.
