With a cast like this, I expected great things but Double Negative is a disappointment at best and a lousy thriller at worst. The film simply does not make sense even after seeing it twice. It's about a writer (Michael Sarrazin) trying to figure out the facts behind the death of his wife. Susan Clark plays his lover and Anthiony Perkins plays a mysterious man who connects the two of them. Actually, Perkins is probably the most interesting part of the film, which is not a difficult task. Some SCTV faces pop up for about a split second and the finale fails to clear up several questions. Double Negative has some great shots of Toronto in winter.
