Factual error: Jack lives in suburban Detroit, yet there are palm trees along the streets.
Factual error: When Beeks is locked in the cage with the gorilla, it reacts in an overtly aggressive and sexual manner. First, gorillas are shy and gentle creatures. The male gorilla would be scared of him, not the other way around. Second, gorillas identify each other by their smell, and the smell of a female in heat is very specific. Beeks would smell like a horsehair rug and the male gorilla wouldn't be the slightest bit interested.
Factual error: When we first see Fatima Blush, she is waterskiing. She is doing several stunts, which are only possible with one ski, the most notable being skiing backwards with one foot in the air. However, when she releases the tow rope and skis up the ramp into James Bond's arms, she is on two skis. (00:45:55)
Factual error: Shirley MacLaine and Jack Nicholson both live in River Oaks (very ritzy neighborhood in Houston) and are traveling to Brennans restaurant in downtown Houston maybe 5-10 miles away - but they go by way of Galveston which is about 45 miles south of Houston - which needless to say is way way out of the way... (00:50:40)
Factual error: During the St. Louis part, they show the Griswolds crossing the bridge into Missouri and *then* getting lost in what they title "East St. Louis." East St. Louis is actually in Illinois, so they would have encountered it before crossing the bridge. This has apparently been corrected in the video version.
Factual error: The movie was set in the mid-to-late 1940s, however, the red wagons shown in the display in Higbee's corner window at the beginning of the film, bear a Radio Flyer script logo which was designed in 1967. (00:03:10)
Factual error: Part of the movie takes place in Vienna, Austria. Although the number plates of the cars are like those in Austria at that time, neither the road markings nor the street car which can be seen when both Steve Martin and Kathleen Turner are "climbing" outside their hotel look like those in Vienna.
Factual error: When asked by the Princeton interviewer what he plans to major in, Joel replies "business." Princeton does not offer an undergraduate degree in business.
Factual error: The caption says "twenty years later" before the main part of the movie starts. Now judging by the dates we've seen on-screen so far that would be in the reign of William and Mary, not Queen Anne.
Factual error: The supercomputer has the British spelling 'Defence' written on it, instead of the American 'Defense', even though the movie takes place in the USA.
Factual error: When they drive away at the end they say they are going to the Valley Sheridan, but when the camera pans out they are really going in the opposite direction towards Santa Monica. (01:35:35)
