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: 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. But 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...

Factual error: The Amtrak Metroliner has open passenger coaches, not the European-style compartments as seen in the movie. (01:30:45)
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.Christoph Galuschka
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: 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)
