Lynch's masterpiece
This is much more than a psychological thriller and goes deeper than Blue Velvet. It concerns a professional photographer who 'discovers' that he might have killed his wife but only through the videotapes of a stranger who has managed to film them having sex in the privacy of their home without them knowing it. We watch as the husband slowly slides into extreme mental paranoia.
When I first watched it I was unable to take my eyes off the screen and searched for months to find a copy. This is a cult film of the noir.
