This chapter reviews the final scenes of David Cronenberg's Shivers (1975). In a character's description of her ‘very disturbing’ dream where she found herself ‘making love to a strange man’, the original line was supposed to be ‘making love to Sigmund Freud’. Cronenberg made the last-minute decision to change ‘Sigmund Freud’ to ‘a strange man’ in post-production. To make Freud the speaker would have been too blatant an intellectual reference, and would have implied that the film's scenario is explicable in Freudian terms, reducing its power. Martin Scorsese's description of Cronenberg's films in terms of ‘Jungian culture shock’ is particularly apt in the case of Shivers; throughout the film one notices hints of something less rational, with less pretence to scientific thinking, than the ostensible cause-and-effect narrative has accounted for. Cronenberg is a modern, and modernist, filmmaker, and requires a solid empiricist runway for his flights of fancy, but he is a filmmaker of the irrational, of dreams that become nightmares. It is for this reason that his works of fantastique are closer to horror than to the science fiction they often resemble.
