Reportedly, Charles Bronson's salary on this picture was US $400,000.

The movie's working title was 'The Night Visitors'.

This movie was made and released about eleven years after Richard Matheson's source novel 'Ride the Nightmare' was first published in 1959.

When Fabienne takes ice cubicles out of fridge by one hand and holds the ice "vase" in another we can clearly see that ice amount isn't enough to feel even the half of the "vase". However in the next frame after dropping ice in the sink she walks out of the kitchen with the "vase" overfilled with ice cubicles.

During the chase, the odometer reads 156.9 going into 157.0. After a few minutes of more driving, the odometer is shown again this time as 157.1, where it left off a few minutes earlier.

Joe Martin: And you and Michelle. What will you do while I'm away?

Fabienne Martin: Killing him wouldn't be murder; it would be like cleaning a cesspool.

Captain Ross: This is a stomach wound; stomach wounds bleed internally.
