Jim Cummings, the voice of iconic characters such as Winnie the Pooh, Tigger, Darkwing Duck, Pete, Ed the Hyena, Ray the Firefly, Hondo Ohnaka, Dr. Robotnik and a variety of other animated characters, provided the vocal effects for the titular machine and was glad to get to work with director Tobe Hooper, whom he was a fan of, but felt that the strain put on his throat by making the Mangler noises and the quality of the film itself wasn't worth the effort. He once saw the film on television and was amused to see that his name was misspelled as 'Tim Cummings' in the end credits, as it meant that he got paid to do a bad film and no one would even know he had been involved.
Although the movie was filmed in London and South Africa, it takes place in Maine, as most of Stephen King's stories do.
There is a gate in the background in one of the beginning scenes, after Sherry initially hurts herself on the clamp. A banner on it reads "labor makes you free". This is the translation of Arbeit Macht Frei, the sign on the gate of Auschwitz concentration camp.
The character of the Pictureman, the police photographer seen in the film is the same actor playing the young casual minded Mortician in heavy make up.
