There are no female characters in the film. The only female presence in the movie is in the voice of MacReady's chess computer and the contestants seen on the game show that Palmer watches. A scene containing a blow-up doll was filmed and then left on the cutting room floor. Additionally, one of the crew was a woman but she fell ill during the outdoor shoot and was replaced with a man.
The Norwegian dog in the film was named Jed. He was a half wolf/half husky breed. Jed was very obedient, never barked and acted perfectly on cue for his scenes.
The Norwegian camp scenes were actually the charred remains of the American site from the end of the film. Rather than go to the expense of building and burning down another camp, Carpenter re-used the destroyed American camp.
The film was originally banned when released in Finland.
