Corrected entry: Donnie bowls a nine in his final frame then sits down for a while. He should have tried to pick up the spare.
Correction: Donny was shown to be bowling strikes all throughout the movie and is visibly upset about not getting the strike on this frame. Either he sat down for a while because he was upset about not getting the strike, or it was his third turn in the 10th frame and therefore was not able to attempt to get the spare.
Corrected entry: Right before the Dude is taken into the Malibu Police Department, the cop car pulling up behind him is, at the oldest, a 1992 Ford Crown Victoria, which would not be available during the film's late 1990 setting.
Correction: The film takes place in 1991.
Corrected entry: In the scene near the beginning it shows a big guy converting a 7-10 split and celebrating. If you watch it closely you will realize that the 7 pin is lined up too far to the left and the ball is already in the gutter when it hits the pin. If this guy is that good to convert the split, then he should realize that it wouldn't count anyway because the ball is already in the gutter.
Correction: This is entirely your assumption: maybe he was practicing and just wanted to see if he could still do it. Maybe he didn't care.
Corrected entry: At the beginning, when the Dude is getting pushed into the bathroom by Jackie Treehorn's goon, right before the Dude gets his head dunked into the toilet, you can see that his hair is already wet.
Correction: The Dude's hair is not actually wet - it looks different than in the previous shot because it is a stunt double wearing a wig.
Corrected entry: Towards the end of the scene where The Dude and Walter are spreading the ashes of Donny on a cliff, a person can be seen walking into view on a cliff in the background around the time Walter says, "Let's go bowling."
Correction: This has already been corrected. They are in public and it's just a man out for a stroll along the cliff.
Corrected entry: The 'marmot' that the Dude is threatened with in the bath is actually a ferret.
Correction: The Dude doesnt know what a ferret is and was stoned at the time so calls it a marmot.
Corrected entry: When Maude Lebowski is getting out of her painting harness, it appears as though she is completely nude until she puts on her robe. However, if you zoom in, you can see that, while she is topless, she is wearing flesh colored panties.
Correction: You can see the panties from the time she's in the harness to the time she's in her robe, so I don't see how it's a mistake.
Corrected entry: As The Dude enters his apartment for the first time, he is not wearing sunglasses. One of the thugs grabs him and shoves his head into the toilet. When they let him go, he fishes out a pair of sunglasses.
Correction: The sunglasses are on the top of his head.
Corrected entry: When The Dude first sees Bunny she is painting the nail of her big toe and the other toes on that foot (her right) have not been painted. When she asks him to blow, a few seconds later, all 10 toenails have been painted.
Correction: All toes are painted.
Corrected entry: When Walter and the Dude are leaving the bowling ally when the cops are coming, we see the dog trailing behind Walter. He never puts the dog in the car or the carrying case before he and the Dude pull out.
Correction: The back door of the car is open for quite a long time while Walter is talking and putting the carrier and his ball in - there is plenty of time for the dog to jump in, and the dog appears to be well trained so it probably did so.
Corrected entry: Walter is twenty minutes late for a league game against Smokey's team. Before he ever gets up to roll, he has pulled a gun on Smokey and The Dude states that they're calling the cops. In the next scene, Walter and The Dude get into his car as the LAPD arrives. How fast did Walter bowl ten frames? How slow is the LAPD?
Correction: This is obviously a stab at the LAPD's infamously slow reaction time.
