Factual error: The tubing scene was filmed at Nashoba Valley in Westford, MA. The scene looking down from the top of the tubing run has a banner with the name of the ski area and the "mountains" in the background scene are photoshopped in.
Other mistake: When Rodrick and Greg bought groceries, there was one bag of "Cheez Curlz" and it ended up in the hot tub at the motel. They weren't shown buying another bag yet they had one when the pigeons "attacked."
Character mistake: Pete says that Terry Bradshaw's corvette is a '75 stingray. It is actually a 1981 or 1982. 1975 corvettes had a rear window that was perpendicular to the ground. 1978 and newer had a sloping rear window.
Factual error: The interior of the 747 is too narrow.
Suggested correction: There is nothing that indicates the airplane is a 747.
Continuity mistake: When the Gunslinger rescues Jake in the forest, he fires far more shots than we see his gun is capable of holding when he reloads it.
Factual error: Before and during the Marines' arrival in Marjah, some of them are wearing Dust Goggles. These would've been first issued in World War II and continued into the early 2000s. The Battle for Marjah took place in 2010, by which point these goggles had been replaced by superior models such as ESS for some time.
Other mistake: Despite the up-to-date equipment used in the movie, Kate carries an old style film camera rather than a dslr. It was obviously so that she could develop the film later to realise her 'love'. At any rate, when going through her bag, she finds a roll of 35mm film to develop, but when the film is laid out on the light table for her to examine with a loupe, the film shown there is not 35mm. I think it was 126mm.
Continuity mistake: When Shawn first holds up the jerky to distract the guard dog, he's holding the torch in his right hand and the bag of jerky in his left. We cut to a wider shot and the items have instantly switched hands. (00:26:50)
Revealing mistake: Back at his NAACP homebase, Marshall meets with the boss who is already sending him to deal with another case. In the close-up of the newspaper he's reading, check out between the actor's fingers. You can tell that half of the article, which begins in English, suddenly switches into Latin 'lorem ipsum' filler text. (00:06:20)
Continuity mistake: Gargamel finds out of the smurf he captured is Smurfette. She grabs the bars of the cage, but the position of the door hinges changes, switching from her right to her left, back and forth. (00:13:35)
Continuity mistake: When Tommy and Greg get into the limo to head to the premier, there are boxes of The Room merchandise and promotional material scatted all about in the limo and filling the driver side of the back seat. But in the shots after they drive past the theater, the seat is suddenly completely empty with all those boxes disappearing. They are also missing in several of the close ups of Tommy, then back in others. (01:20:15 - 01:21:00)
Continuity mistake: When Billie Jean hits the winning shot against Bobby Riggs, she is inside the square closest to the net. However, when she throws her racket in the air in victory a second later she has moved outside the box, close to the center of the court.
Visible crew/equipment: When "James" begins to repeat his "dark and stormy night" story to Carolyn it then cuts to him leaving her home, and just as Carolyn shuts the front door, the reflection of the moving boom pole can be seen on the glass window to the right. (00:31:20)
Factual error: Ronnie Knight is shown being released from "HM London Prison." There are several prisons in London. None of them is or ever has been called "HM London Prison" (or even the correct form, "HM Prison London").
Factual error: When the astronaut is being questioned by a 3-star general, he keeps referring to the officer as "colonel", in fact the closed captioning does the same.
Continuity mistake: During the shooting between Bats, Darling and Buddy with the guy in the white suit and the "cops" Darling gets shot in the right arm then she keeps shooting and moves back, but in the next shot she is at the front again.
Continuity mistake: At the beginning of the movie, Jamie Fox is stabbed. He goes to the men's room and the wound is on the right abdomen area as he applies the dressing to it. The rest of the movie shows him holding the left side of his abdomen area and the blood stains on his shirts also are also on the left side. (00:16:50 - 00:45:30)
Audio problem: There are American crows (Corvus brachyrhynchos) calling in the distance during the initial pursuit for Quan in the forest behind the Belfast farmhouse, right after the trap door scene ends and we see two of Hennessy's men share a look. American crows do not exist in Ireland - only hooded crows, carrion crows, rooks, ravens and choughs.
Continuity mistake: The license plate on the Mercedes driven by Vers Lockman changes from New York to New Jersey and back to New York. (00:25:20 - 00:31:23)
Continuity mistake: Batman plans to put the Joker in the phantom zone, and Barbara says no. She is still right in front of the SUV, but in the next shot, she is suddenly standing more forwards.
