Revealing mistake: Right in the beginning of the movie, we see young Viktor holding a gun to a young girl, about to shoot her. The gun is a revolver and as it comes into focus, you can see there are no bullets in the gun. This is part of a later scene in the movie where Viktor kills his first two people. As he's shooting, you can again see there are no bullets in the gun. (00:01:20 - 00:23:10)
Deliberate mistake: When the cop car is ramming the back of the trunk of Dorff's car, you can tell it is a Ford. The filmmakers however, have put gaffer tape over the logo.
Factual error: The pirates' map shows a drawing of Tower Bridge, which Pirate Captain sees through the telescope moments later. Construction of Tower Bridge started in 1886, and it was completed in 1894. Queen Victoria was 73 when Tower Bridge was completed, whereas she is in her late twenties or mid thirties here. The sign setting the film in 1837 also makes no sense given this timeline. (00:25:20)
Other mistake: When Ida is with Prince, in some of the closeups Prince is wearing a custom halter noseband with "Sky High Angels" embossed on the leather. The "Sweethearts of the Rodeo" rodeo stunts featured in the movie were performed by the "Sky High Angels" a real rodeo drill team, and Prince was played by Hank, an equine member of the "Sky High Angels."
Visible crew/equipment: As Jack and George enter the boat site they hide behind a red Jaguar XFR. As the camera moves round the camera man is visible in the chrome-work on the Jaguar. (01:35:20)
Character mistake: In the scene where Debbie is sitting in Dr. Pellegrino's office, she finds out she is pregnant. Dr. Pellegrino's name is spelled Pellagrino on his white medical jacket and Pellegrino on his desk.
Continuity mistake: When Benedick is listening to Don Pedro and Claudio from outside the house, his close ups are in the sun and the wider shots are in shadow.
Continuity mistake: At the battle of the bands Ryan's car is smashed by Tyler and his friends, specifically the windscreen and headlights. When Elissa drives the car minute later, it is in perfect condition. It's also in perfect condition when Ryan later reverses it into the garage.
Factual error: Lee gasses up his car on the Garden State Parkway while driving Imogene to NYC. Never has there ever been self-serve gasoline in the state of New Jersey.
Revealing mistake: When Picasso removes the first finger from Fan Yau Lee's hand, you can see that there is no blood on the instrument used.
Factual error: When the main character goes into the church, she looks at a picture from 1989 labeled "annual picnic". In the picture a boy (next to the main character's mother) wears a hat with a DC (DC Shoes) logo on it. DC Shoes was established in 1993. (01:00:00)
Continuity mistake: Once Ben and Amy are reunited, he gives her some money and tells her to go as far away as she can go, with her protesting. During this, he places his hands on her head to look at her. When the angle changes from showing her to him, his fingers are positioned differently each time. (01:34:25)
Deliberate mistake: When the grandfather clock chimes at 12:00, look at it when the clock ticks. It starts at 11:58 but then ticks to 12:00. The clock has somehow ticked 2 minutes instead of 1 minute.
Continuity mistake: Ewan and Mark are seen drawing their guns outside of Paul's house with silencers on. As they enter the house, the silencers are off. Once Ewan is upstairs, and Mark goes outside to look for Paul, they are back on the guns.
Continuity mistake: Before making the big deal, Tony tries to show Frank a round house kick and winds up breaking his foot in the attempt. Frank has a cigarette in his right hand. He then reaches down to get the drugs from Tony, without his hands moving together, and suddenly the cigarette is in his left hand. (00:25:40)
Continuity mistake: When John catches the bat and then lunges forwards his wife, you can see from the angle behind her she has her left arm up trying to block him, as it does a slow motion pan around. It cuts to the reverse angle as John goes in for the kill and her hand is suddenly down when John kills her. (00:02:25)
Continuity mistake: The main character alternates between driving a Ford probe and a Saturn throughout the movie. (00:15:00 - 01:00:00)
Factual error: The beginning scene of the film is supposed to be in 1984. An Alf lunch box can be seen being carried by one of the students and Alf wasn't on the air until 1986.
Factual error: The VW Bug that the belfry falls on is a later model than 1965 when the movie is set. The larger tail light with yellow on the lens seen on the VW in the movie didn't come along until 1968. The one in the movie may even be of early 70's vintage.
Continuity mistake: While Timothy is saying goodbye to his girlfriend, the girl's birthmark disappears in the shot.
