Cujo

The dogs featured in the film would often have their tails tied down to their legs because the animals would be visibly enjoying themselves so much that they would wag their tails during filming. This tactic was missed once in the editing, where one shot clearly shows Cujo from behind, growling and supposedly ready to attack, but wagging his tail energetically. Such is also the case about 54 mins. in, after "Cujo" has finished his first kill: the dog must have broken out of its tail restraint, as it's wagging it unusually low, yet happily.

During the first night that Cujo has Donna and Tad trapped in the car, Cujo becomes enraged by the ringing phone and crashes through the window to attack it. When the phone stops ringing, Cujo remains in the window, and you can see the trainer's hand come up and pull the dog down from the window.

The film's title appears out of a pool of swirling blood.

The original VHS release of the film, as well as the television version, omitted some early scenes in the film establishing the characters. Among the scenes cut are a scene of Vic Trenton and Steve Kemp playing tennis, a scene where Vic picks up Tad from daycare, and a scene where Donna and Steve are in bed and Steve starts playing a trombone while Donna gets up and goes to dress in the next room. This last scene replaces the more subtle scene of Donna and Steve making love that is featured in the VHS release.
