This movie was notable for its time, for its use of an electronic and avant-garde music score, which, when heard in theaters in Dolby Stereo, was aurally separating and distorting. Reportedly, forty different music tracks were used for the sound.

Producer Jeremy Thomas once said of this movie: "Because I had a great director, and a quality piece of literature I managed to get a wonderful cast such as John Hurt and Alan Bates. Skolimowski had a sense of shooting style then, this was the second director with whom I had worked closely, and it was fascinating watching Skolimowski work. He came from a Polish tradition, the Wajda Film School, he had a different background to other directors with whom I had been working in the cutting rooms or elsewhere, and it made the film much more creative to me. I saw it more as an artistic endeavor by him. The film went to Cannes and won the Grand Prix de Jury. We were incredibly lucky, and the film was appreciated by the jury. It was a very small festival then, nothing like the Cannes Film Festival of today, it was a small event in a cinema of eight hundred people or so."

Nicolas Roeg was asked to direct, but was unavailable.

This movie was nominated for the Palme d'Or at the 1978 Cannes Film Festival. It tied with Bye Bye Monkey (1978) for the Grand Prix de Jury.

When Rachel first sees Crossley in the kitchen a figure of a bee is shown hanging over him. From that moment on any time Crossley is "preying" on Rachel the sound of a buzzing bee can be heard.

Anthony's (Sir John Hurt) recording studio is decorated with clippings of Francis Bacon paintings. One of these paintings is "Paralytic Child Walking on All Fours" which the film pays direct homage to later on when Rachel crawls across the bedroom floor and the image briefly becomes drained of color.

The chilling aspect about Crossley's (Sir Alan Bates') shout was that it had the power to kill. "The Shout" of the title can be defined as being a "death shout".
