National Lampoon's Christmas Vacation

Corrected entry: There is no way all of Clark's lights would cause an overload to the power plant. His house's main breaker would have tripped a long, long time before that could happen.

Correction: This is an over the top comedic effect. Not meant to be taken seriously.

Corrected entry: When Clark is in freak out mode and cuts down the tree between his and the neighbor's house, Todd and Margo are inside eating a quiet dinner. Under normal circumstances, they would have heard the chainsaw.

Correction: They're obviously used to Clark doing odd things. They likely thought nothing of it.

Jason Hoffman

Corrected entry: The Christmas tree is still visible after it has burnt down.


Correction: When? In what scene? It's a charred skeleton after the fire, then Clark immediately goes out and replaces it with a tree from the yard. You need to be more specific.

Brian Katcher

Corrected entry: When all the family is outside to see the christmas lights, there is an aerial shot of them. Clarke starts to say "Joy to the world" before you actually hear him say it. (00:26:20)

Dr Wilson

Correction: Clark is not trying to say "Joy to the World" in the overhead shot, he is vigorously moving his head to elicit more louder and enthusiastic "drum rolls" from his skeptical in-laws and parents. Further, the next shot of him (before he turns the lights on and actually sings "Joy to the World") shows him comically moving his mouth to simulate the drum rolls he is getting from his family.


Corrected entry: When Clark is driving next to the old truck you see him floor the gas pedal. It's a Ford Taurus and the truck is old and hardly running, but in the next frame it's accelerating quickly past the car.

Correction: Just because the truck is old and beat up doesn't mean the guy driving it doesn't take care of the engine.

Jason Hoffman

Corrected entry: When the Griswold family are going to buy a christmas tree, they are in the mountains. There are no mountains near Chicago, where the Griswolds live.

Dr Wilson

Correction: It's unknown how long they've been driving on the road so they more then likely drove somewhere in or near Illinois to get their tree like the Cascade Mountain or the Chestnut Mountain. Both of which are a mere three hour drive.

Correction: The driving scene towards the Christmas tree farm appears to very closely match the area approaching Wisconsin Dells, a very popular summer and winter resort area that is a 2-3 hour drive from Chicago - and also home to many Christmas tree farms.

Corrected entry: When Cousin Eddie barges into the house with Clark's boss, Ellen jokingly tells him this is the family's first kidnapping, which is actually wrong. In National Lampoon's Vacation (1983), Clark holds the security guard at Walley World hostage, and forces him to take the family on the rides.

Correction: First, that was the joke. And Ellen wouldn't admit that the family has a history of kidnapping people and would lie.


Corrected entry: When Clark is hiding the gifts in the attic he finds an old pink one, but the shot later, it is blue.

Dr Wilson

Correction: The next shot is not of Clark holding a blue package, but of Francis wondering why it's so cold, discovering the stairs are down, then closing them. That is plenty of time for Clark to discover another hidden and forgotten package from the past, which happens to be a blue one, now.


Corrected entry: When Clark goes around the side of the house to see why the lights don't work, one of the mothers goes in the garage and flips on the switch making the lights go on. Considering Clark covered the whole house with lights, he would've seen them come on.


Correction: The running gag in the Vacation movies is how oblivious Clark is. This is simply a joke pointing that out. He even thinks he figured out what was wrong without noticing the lights came on.


Corrected entry: I've noticed in a couple of scenes where Chevy Chase and Beverly D'angelo are standing in the front hallway of their house, you can see the wooden rafters of the ceiling of the set in the dining room. (00:19:15)

Correction: This is part of the ceiling, not part of the set. Some people choose to have exposed beams in their homes.


Corrected entry: When Clark gets locked in the attic he tries to open the door and calls out "Rusty" Then he calls out "Bev" instead of "Ellen".

Correction: He doesn't call out Bev, he screams "heeeeeeeelp." It then cuts to the outside with the rest of the family so his "help" call gets cut off.


Corrected entry: Leaves can be seen on several trees around the Griswold house, which is supposed to be in Chicago and its obviously supposed to be wintertime.

Correction: We sometimes have leaves on some of our trees all the way through winter. They only fall off with extreme winds.


Corrected entry: Why do they make Russ and Audrey sleep in the same bed in the spare bedroom when Ellen's parents get to sleep in separate bunks on Russ' bunk bed? This makes absolutely no sense.

Correction: Couple of reasons: Audrey may have had a fit at the idea of sleeping in her brother's room, and also the grandparents may not be sharing a bed anymore. Many older folks (my grandparents included) stop sharing a bed as they get into advanced age due to one partner's nighttime habits disturbing the other.

Corrected entry: When the grandparents are all sleeping and snoring in the chairs, the TV is showing the Macy's Thanksgiving Day parade which is shown on Thanksgiving Day. Not a week before Christmas. (00:21:00)

Casual Person

Correction: That's not the Macy's parade. It's the Chicago Christmas parade. Not sure if they still have it anymore, but they used to do one.

The parade on the TV is in Detroit near 1 Woodard ave.

Correction: It's entirely possible they're watching it on tape. As a child, my aunt used to record the Thanksgiving Day parade every year.

Jason Hoffman

Corrected entry: When Clark Griswold is on a ladder putting Christmas lights up on his house the trees in the background are green and leafy, (not evergreen trees), indicating summertime, although there is snow on the ground and it is supposedly winter. (00:21:38)

Correction: As Clark climbs the ladder, all of the tall trees behind the house have no leaves and are even covered with snow. The bush that does have leaves next to the evergreen, beside being the only thing with leaves, could easily be any number of plants that retain their leaves throughout the winter.


Corrected entry: In the opening scene where Clark and the two guys in the pickup are racing, Clark pulls under a 18-wheeler. In the close up shots, you can see the truck's tyres from under the truck, but in the far away shots, you can see the safety bars that were put under the truck for the stunt driver so he wouldn't ride up under the truck.

Correction: There are no bars or any other special enhancements that were done to the truck for this stunt. The only visible bars in the close up and far away shots are the ones that hold the mudflaps in the front and the same bar across the back wheels that's seen in all of the shots.


Corrected entry: When Clark is going up in the attic, he has a bag with two gifts in it. As he goes into the attic, there are three gifts in the bag.


Correction: We never see the contents of the bag as he's going to the attic and up the stairs. All we see is that he's carrying a large bag with some bows & ribbon coming out the top. There is no way to see how many presents are in the bag.

Jason Hoffman

Corrected entry: At the beginning of the movie, when the Griswold family are in their car under the wood truck, everybody panics but not Russ, who sings or something like that. (00:06:30)

Dr Wilson

Correction: Character choice: He's used to this kind of thing from his dad.

Jason Hoffman

Correction: I just watched this scene. Rusty isn't losing his mind or anything, but he is obviously scared/worried. His lips are quivering, which may be what you think is singing. He is certainly not happy with the situation.


Corrected entry: In the scene where Eddie is introducing Snots, the first shot has the dog perfectly clean, but when Eddie explains why that is his name, in the next shot he is covered with snot.


Correction: When the camera is on Eddie explaining his name, you can hear Snots sneeze thereby covering himself with snot.

William Bergquist

Corrected entry: Right before the grandma (Doris Roberts) faints due to the squirrel, Eddie's kids are on the brink of laughing before the scene cuts. Everyone is supposed to be scared.

Correction: Everyone might be scared at first, but once over the initial shock, kids could easily find the adult's panic amusing.

Grumpy Scot

Factual error: In the scene where Clark is working on the lights the full moon is shown. This is December 14th according to the advent calendar. On December 24th when Santa's sleigh goes sailing over the moon, it is still full.

Clark: Worse? How could things get any worse? Take a look around you, Ellen. We're at the threshold of Hell.

Trivia: Clark Griswold in the attic watching old movies dressed in a woman's turban and gloves to keep warm is not only funny but a reference to the Norma Desmond character from "Sunset Boulevard", who watches her old films to remember her Hollywood glory days.
