Trivia:
In the close up shot of the United States National Science Institute Station 4 sign, a 'Smokey the Bear' sign can be seen.
In the scene where Norris' (Charles Hallahan) head separates from his body, special-FX designer Rob Bottin used highly inflammable materials for the construction of interior of the head and neck models. During the shoot John Carpenter decided that, for continuity reasons, they needed some flames around the scene. Without thinking they lit a fire bar and the whole room, which by now was filled with inflammable gasses, caught fire. Nobody got hurt, but the entire special effects model, on which Bottin had worked several months, was destroyed.
Donald Pleasence was the original choice for the character of Blair. Pleasence was unable to perform the role due to a scheduling conflict.
The film was originally banned when released in Finland.
For a scene where a character's arms are severed, a real-life double amputee stand-in was used wearing a mask in the likeness of the character. The audience focuses on the bloody stumps while the mask goes unnoticed.
