Other mistake: Packie arrived at Frank's garage on a bicycle, wearing a brown coat, hat, gray hooded sweatshirt, patterned shirt, and a T-shirt. Swaino arrived on a motorcycle, wearing a tight jacket, no hat, black gloves, and black jogging jacket with white trim. When they were outside by the grill, they had large sweaters over their coats. It isn't known where these sweaters came from. It can be assumed the blanket Swaino used at first was from Frank's garage, but the sweaters did not appear to be Frank's. (00:25:32 - 00:37:35)
Revealing mistake: When Alana is walking toward the students, the hedges are mostly dark green, sheared level across the top, and reach to her elbows. Later (after Gary tells Alana he will take a mirror), the hedges turn mostly yellow and flower-like across the top, are quite uneven, and are as high as her shoulders in spots. (Use of a green screen is apparent). (00:00:40 - 00:01:26)
Suggested correction: One look at the scene make it apparent this entry is totally incorrect. The bushes look natural. The yellowness is just colour grading. There is no sign of green screen usage whatsoever. It would make no sense for this film, especially if you realise that director PT Anderson is known to be very much against the use of any sort of VFX or green screening.
Plot hole: Kyle got a flat tire and there was no cell phone reception to call for help, so he and Julia decided to walk to the Ghost Town. However, almost all vehicles - especially a relatively new SUV like Kyle's - have a spare tire. Kyle surely had a spare and could have at least tried to change the tire himself. (When Kyle saw his damaged tire, he complained that it was a $300 loss, not that he did not have a spare tire with him). (00:04:55)
Factual error: Morse code is supposedly being transmitted by the blinking street lights. They supposedly spell "For 3veryth5h1ng that 7iv3s is holy." I know Morse code. It was just a random scattering of letters. (01:00:05)
Continuity mistake: Max Cameron's classroom appears to be slapped together and inconsistent. The wall is white but later tan. The door hinges are on the right, then left. The pencil sharpener, awkwardly mounted on the door frame, gets moved to the right. The hallway is a tan wall, but later just a closed door. Doors comprise the wall behind Dewey and there's a door behind Max, to the right of the white board. (00:59:55 - 01:00:43)
Factual error: During the escape from the farmers market a red London bus is in the background. Those busses aren't used in Gloucester.
Revealing mistake: When Jake is sliding on the floor at the mall trying to grab his retainer, streak marks are visible on the floor from where they practised the shot.
Plot hole: Alberto didn't sign up for the Portorosso Cup, and he enters anyway. This should've gotten Luca disqualified.
Continuity mistake: The angle of the laptop on the kitchen table changed (and no-one was close enough to have moved it). The laptop was initially more evenly aligned with the edge of the (round) table. A little later, the laptop was not visible, but probably should have been. (00:04:09 - 00:04:44)
Revealing mistake: During one of the chase scenes, an SUV hits a rock barrier and flips over landing on its top. The car spins around, and we see that it is empty. The driver then climbs out as if he was just in the vehicle.
Factual error: Unless left in the vehicle (not the case here), towed impounded vehicles do not have keys. Moreover, lacking keys, a valid registration, possibly proof of insurance, and new plates, vehicles bought at a NYPD auction are to be TOWED away. A newly-purchased auctioned vehicle, such as the Navigator in the movie, is "ticket-" or "citation-ready", not ready to be driven on the streets.
Continuity mistake: At the beginning of the movie, the real estate agent greets the McKenzies, lovers of all things open. The potential clients hold the papers in a completely different way at the cut ("I was just telling the Breckins that..." etc). (00:01:15)
Continuity mistake: Samantha placed the bottle of glue on top of the metal object she glued, but the bottle of glue was on the desk and the metal object was gone when the doorbell rang. (00:04:56)
Continuity mistake: The changes/inconsistencies in how the lobsters were arranged on Frank's and Hildy's plates cannot be accounted for based on their movements while eating/cracking them open. (00:59:35 - 01:00:37)
Revealing mistake: When Julie is running around the city whilst all the extras are stood frozen, there is a moment where she is walking next to a small park, before beginning to turn right and run down a road. Once she runs onto the sidewalk after running down the road, two girls can be seen stood on the same sidewalk holding hands. The girl on the right can be seen moving her right hand ever so briefly, even though the extras are all supposed to be standing completely still. (00:54:35)
Character mistake: After banker Karl was reported missing from his home, the police detective did not even think to locate his car - which he could have merely driven away in (meaning he was not kidnapped).
Continuity mistake: The amount of red beverage in June's bottle changes several times, from up to the curved part of the plastic bottle (lower amount) to below the neck and up to the neck (almost full). Front views of Mikey show the level of the drink higher than views toward June. (00:17:07 - 00:18:51)
