Factual error: In the very beginning sequence, as the riders are galloping triumphantly across the mighty windswept plains of yore to capture Conan, you can see power lines in the background in one brief shot at the very left of the screen.
Factual error: When Glen and Nancy are talking on the bridge, you can see huge palm trees in the background. Though this was filmed in California (hence visible palm trees at the cemetery), the fictional Springwood is supposed to be in Ohio - they show the location of Springwood on a map at the start of 'Freddy's Dead, the Final Nightmare', and there's no other conflicting in-universe location given within the series. So it's established as Ohio, but there are no palm trees in Ohio. Other California "hints" add to the mistake, such as CA license plates, etc. (00:01:00 - 00:43:22)
Factual error: For a movie supposedly set in late December in a Northern state, all of the deciduous trees still have leaves on them. The most obvious place to see this is in the opening scene, when Billy is trying to start his car in front of his house. (00:07:05)
Factual error: When the TV store is closing at Bloomingdale's, The Richard Simmons Show is shown on the monitors. In 1984, when the film is set, this show was broadcast only in the morning and was not released in syndication. The show would therefore not have been playing on a television channel in New York City in the late evening.
Factual error: The tigers used here are Indian Bengal tigers and this is set in Africa. Plus zebras can't be ridden as Sheena's able to do.
Suggested correction: The only striped animals in the movie are zebras, not tigers. A tiger did appear on some of the DVD covers, which is an error on the covers. For a fantasy movie, riding a zebra falls under artistic license. In any case, the zebra Sheena was riding was a small horse with makeup to make it appear to be a zebra.
Factual error: In the scene where the convoy is on the way to the Eldridge, the trucks used are M35 deuce and a half dating from 1949, the jeeps used are M151 mutt dating from 1959 (horizontal grills) . (00:05:55)
