Shivers (1975) is the film that proves David Cronenberg arrived fully formed. His debut feature, shot on a budget of just under $180,000 CAD with money from the Canadian Film Development Corporation, announces every obsession the director would carry through Videodrome, The Fly, and The Brood: bodies that betray their owners, institutions that promise safety while manufacturing ruin, and desire stripped of all its romantic insulation. It's a first film with almost no rough edges, at least not the kind that come from inexperience.
What happens in Starliner Towers
The setting is Starliner Towers, a luxury high-rise apartment complex on Nun's Island in Montreal, designed to be a self-contained community. Gym, pool, restaurants, doctors on site. Cronenberg opens the film with a promotional video for the building, all reassuring voice-over and smiling couples, and then cuts immediately to a man strangling and dissecting a teenage girl in one of the apartments. The contrast isn't subtle. It isn't meant to be.
The dead scientist, it turns out, had been working on a parasite that was supposed to function as a replacement for failing organs. What he actually created behaves differently. The organism takes up residence in a host's body, inflames sexual desire to a compulsive, aggressive pitch, and spreads through contact. By the time the building's physician, Dr. St. Luc (Paul Hampton), understands what's loose in Starliner Towers, the corridors are already filling with infected residents.
The parasite itself is one of practical horror's most effective creations. It looks like a large slug crossed with an intestine. When it moves under skin, the effect is genuinely nauseating. Roger Dicken handled the creature effects on a tiny budget, and the physicality of the thing matters: this is a film that wants you to feel the infection as something tactile, intimate, unavoidable.
A blueprint in plain sight
The architecture of Starliner Towers does half the film's work. Cronenberg shoots the building as a grid: identical corridors, identical doors, floors stacked above floors. It should feel orderly. Instead it feels like a containment unit that has already failed. The swimming pool sequence, in which a fully clothed St. Luc wades through infected residents reaching up from the water, is still one of the great horror images of the 1970s. Staged, still, and completely nightmarish.
What separates Shivers from a routine creature feature is the film's ambivalence about its own premise. The infected aren't in pain. They're gleeful, liberated, indiscriminate. Cronenberg allows a reading in which the parasite represents not pure evil but a kind of societal id. The clean, prosperous, quietly repressed world of Starliner Towers is replaced by something feral and communal. St. Luc, the film's nominal hero, is himself remote, clinically detached from the people around him. The infection is appalling. The world it replaces is also, quietly, appalling. Cronenberg doesn't resolve the tension, and that's exactly right.
Barbara Steele appears in a small but memorable role as Betts, a resident who becomes infected during a bath scene that Cronenberg stages with real menace. Steele, a veteran of European gothic horror, understands how to hold the camera's attention without doing anything obvious.
The moral panic it caused
When Shivers was released in Canada and then in the United States (under the title They Came from Within), it provoked a genuinely hostile critical response. Columnist Robert Fulford wrote a furious piece in Saturday Night magazine condemning both the film and the Canadian government for funding it, calling it a disgrace to public money. Cronenberg later said the outcry surprised him. It shouldn't have. Shivers is a film that uses the body as a site of anarchic political argument, and it makes that argument inside a setting that is unmistakably comfortable, unmistakably middle-class, and unmistakably Canadian.
The film's release in Britain under the title The Parasite Murders was handled more quietly, but the European reception was warmer. Horror audiences on the continent had already been primed by Italian genre cinema to accept the body as both victim and metaphor. Cronenberg was doing something adjacent, but rooted in colder, more clinical soil.
Why it holds up
Shivers holds up for the same reason most of Cronenberg's early work holds up: the ideas are specific enough that they don't dissolve into generality. This isn't a film about vague fears. It's a film about one precise, horrible thing that happens to a particular kind of contained social space. The high-rise as sealed ecosystem. The body as a system that can be hijacked. The medical institution as the source of the infection it claims to treat.
Forty of the film's 87 minutes are pure escalation, and Cronenberg manages them without repetition. Each infected encounter has a different texture. Some are frightening. Some are darkly comic. One, involving a child, is deeply unsettling in a way that would be hard to get past a modern studio. The film trusts that its audience can hold all of those registers at once.
The ending offers no catharsis. St. Luc is overwhelmed. The infection spreads beyond the building. The final image shows cars leaving Starliner Towers, carrying the parasite outward into Montreal. Cronenberg doesn't frame this as tragedy. The film's last shot is almost peaceful. That's what really disturbs.
A starting point, not a footnote
Critical writing on Cronenberg tends to treat Shivers as a rough precursor, something to cite before moving on to Videodrome or The Fly. That's a mistake. Shivers is not a prototype. It is a fully achieved film that happens to be a first film. Every Cronenberg theme is present and operational: the body as territory, the collapse of institutional authority, sexuality as a vector for transformation and violation. He didn't develop these ideas over his career. He arrived with them and then refined the craft to carry them.
Watch it in context and it reads as the beginning of a genuinely coherent body of work. Watch it alone and it reads as one of the most unsettling films produced anywhere in the world in 1975. Both things are true at exactly the same time.
