The McGuffin (1986)

Paul Hatcher has a habit of spying on the neighbors across the way, something that gets him into deep trouble. Hatcher is a movie critic, and for awhile it looks like his main problem is keeping reality and the silver screen separate. But then a double murder occurs across the street after some mobsters cannot find an incriminating negative. After Hatcher discovers where the negative is hidden, he is bumped to the top on the assassins' hit list.
