The love-making scene features Richard Neville and his then girlfriend Louise Ferrier. After filming it was discovered that the sound had failed, and so the crew asked the couple to redo the scene, sound only. Rather than making love, they sat on the bed, and read William Blake poems to each other.
The love-making scene involving real-life partners Richard Neville and Louise Ferrier caused some controversy when the film was first shown. However, a member of the crew (anonymous) was quoted by the satirical magazine "Private Eye" as saying that "Neville's reputation was saved in the cutting-room!"
