Making a rare visit to Canada, Claude Chabrol cowrote and directed the low-pressure psychological melodrama Blood Relatives (Les Liens de sang). Donald Sutherland and Donald Pleasence head the cast in this story of the aftermath of a brutal murder. The victim, a 17-year-old girl, was apparently raped before she died, leading Carella (Sutherland) to believe that she was killed by a sex maniac. Pedophile Doniac (Pleasence) tops the suspect list, but don't be too sure. The truth is much "closer to home" than anyone realizes at first. Lisa Langlois, who made something of a career of Canadian scare flicks, makes her screen debut in Blood Relatives; also appearing, is Chabrol's wife Stephane Audran. Blood Relatives was based on a novel by Ed McBain (aka Evan Hunter), of 87th Precinct fame; the film was released in the US in 1981, three years after its completion.
