Factual error: Chill Factor takes place in Montana, at one point the characters argue over whether to go towards Billings or Missoula. Anyone who knows anything about the southwest U.S can see that most of the movie is filmed in or around Monument Valley. Monument Valley is spread across parts of northeast Arizona and southeast Utah.
Factual error: Trying to cozy up to Ike, who she knows to be a Miles Davis fan, Maggie gives him a battered-up LP of Davis's "Kind of Blue" album, which he tells here is very rare. Truth is, "Kind of Blue" is one of the best-selling jazz albums of all time, and is not rare at all. Furthermore, the album and initial CD pressings had been (inadvertently) mastered at the wrong speed; the mistake wasn't corrected until relatively recent CD issues. The long-player is, in other words, virtually worthless on any count, especially in a jacket as beat-up as the one Maggie gives to Ike.
Factual error: When the bloke's head gets cut off in the beginning by the circular saw blade being thrown, surely there would be more blood, like when his mom got killed under the bed?
Factual error: After some tinkering with a TV set and a mirror, Calvin Webber finds that he can watch a TV show in reverse image. On the screen is the opening of "The Honeymooners" showing the cast members' names superimposed on a picture of the moon, with Jackie Gleason's face. But the picture is in color, mostly blue and off-white, while the actual "Honeymooners" series was filmed in black-and-white.
Factual error: The TV station in the movie is KGSC channel 10, and the building shown at the beginning for the exterior shots is in fact Santa Barbara's TV station, but it's channel 3 and its call sign is KEYT. There is no channel 10 in Santa Barbara. In fact, the only channel 10 in Southern California is in San Diego. (00:01:45 - 00:34:45)
Factual error: When the gang follows Ben Ravencrift home, they cross over a long bridge supposed to signify Brooklyn, but is in fact, The Golden Gate Bridge in San Francisco.
Factual error: The way that Charlie makes the skeleton move is way too complex to be controlled merely by a basic remote controller (which looks like it was originally for an RC car of some sort), which can only control up, down, left and right.
Factual error: The British Major at the end has his rank crowns sewn to the collar of his shirt. The British Army didn't/doesn't do that. They should be on his shoulder epaulettes.
