Corrected entry: In the postcards opening, just after Christie Brinkley's name fades offscreen, the postcard for the "Mystery Spot" lists its location as "St. Ignance, Michigan." The Mystery Spot is located in St. Ignace, not St. Ignance.
Corrected entry: When the Griswolds first set out from Chicago, oil field equipment is seen operating in the background before flashing back to the Griswolds taking an off ramp from a major expressway with the Chicago skyline is still in the background. There are no oil fields anywhere near Chicago.
Corrected entry: When Rusty and Dale are talking about what there is to do on the farm, Rusty asks Dale if he has Pac-Man, and Dale says no. But when they are in Dale's room looking at the porn magazines, you can see a portable Pac-Man video game sitting on the pillow behind Rusty.
Corrected entry: When Ellen and Catherine are chatting in the kitchen when they first arrive at their house, the subject of Aunt Edna comes up. Ellen remarks, "Aunt Edna, she's still alive?" In the next scene Edna comes out of the house and says, "You're the ones who sent me the fruitcake, it made me so sick". Why would Ellen send Aunt Edna a fruit cake for Christmas when she thought she was dead?
Corrected entry: When Christie Brinkley first appears, she is supposed to be driving a convertible at over 80 mph, yet her hair is blowing only slightly, as if in a light breeze.
Corrected entry: The family Grizwald car has wobbly wheels when they leave the gas station where the two attendants take all their money but a scene after that they are back to normal again.
Corrected entry: When the Griswolds get lost in the back streets of Missouri, they ask for directions from a local while his gang quietly steals their hubcaps. Firstly, why didn't they just take their luggage which would have been worth more. Secondly, why do they try and hide what they are doing?. Its not like the Griswolds could do anything about it anyway. Yes I know it only a comedy...but come on.
Corrected entry: When Clark falls asleep and drives off the exit, take a look at the top of the exit ramp. You can see police lights flashing which probably tells us the ramp and road was closed so they could film the scene. You can't see the actual lights, but you can see the flashing red and blue. Check it out.
Corrected entry: When Chevy Chase enters the hotel bar, the sounds of a full band can be heard, with bass and drums. But the only musician in the room is the piano player. You can tell because they cut to different shots of him and he is most definitely alone. Also, the audio track is a very complicated piano riff in the right hand but when the pianist's hand is shown he's playing a much slower song than the one heard.
Corrected entry: When driving in Arizona, in the storm, you can see that 3 of the 8 headlights are on, 2 on the left, and 1 on the right. But, the next scene, only 2 are on, 1 on the left, 1 on the right.
Corrected entry: Whenever the airbag deploys in the car, the material used seems to be thin plastic and looks remarkably like a bin liner. Airbag material appears much thicker with a woven texture.
Corrected entry: In the scene in Kansas, where the Griswolds are first meeting Cousin Eddie's family, he introduces them to Daisy Mabel, who was born without a tongue. Only thing is, right before he introduces her, you can see her looking at Clark and sticking her tongue out at him and rolling it around her mouth.
Corrected entry: When the Griswolds are only ten hours away from Wally World, Ellen, Audrey and Rusty all vote that the Holiday has been a disaster and they should turn around and go home. But since they have virtually no money, how would they pay for gas and accommodation on the return trip?
Corrected entry: When the car crashes in Monument Valley after going off the cliff, all the luggage that was on the roof is now on the ground. The impact should have thrown it all forward, yet there are suitcases beside and to the rear of the car.
Corrected entry: In the beginning when they are about to leave for their vacation, they show the car from inside the garage with no suitcases. The next time they show the car there are suitcases on the top of the car.
Corrected entry: In the "edited for television" version, during the visit to Cousin Eddie's, all references to pot smoking, which Audrey recently had discovered, were omitted. This makes for some curious unexplained occurrences later on, like when the kids are getting in the car as the family leaves, Audrey has sunglasses on and is clearly coming off a serious bake, or later on, when pulled over by the cops (when Clark tied the dog to the bumper), Audrey asks aunt Edna to hold her purse. This is clearly because she thinks she may be busted for the pot in her purse, so she plays sick and gives aunt Edna the purse. None of this makes sense in the TV version because we never learn of Audrey's earlier reefer discoveries.
Corrected entry: In the scene where the Grizwolds get lost, then crash the car, the location where they get lost is in Monument Valley. I have been to Monument Valley many times. There is only 1 road going in, and 1 road going out. impossible for anyone to get lost there.
