Visible crew/equipment: When the boys approach the cop car and are trying the doors, the camera crane can be seen reflected off the bodywork of the car.
Continuity mistake: After Thomas biffs the trucks, the position of the way they are derailed changes between shots.
Continuity mistake: Théo shows up in class unannounced. The teacher tells him to sit next to "that girl", mistaking Daniel for one. The classmates of course have a cackle at that; the girl at the desk behind Daniel's laughs holding a pen in her left hand at first, right hand at the cut. (00:08:50)
Continuity mistake: During the fight scene with the contract killer in the apartment building, the killer's coat catches fire. As the scene and fight continues, the coat is no longer on fire. (01:16:30)
Factual error: There are several scenes in a field of barley. Tramlines are seen. Tramlines in crops were invented in 1975 to allow tractors and sprayers to drive up and down fields. Sunset Song is set around 1914, 61 years before tramlines were invented.
Revealing mistake: When Rachel has a red turban on and is supposed to be bald, you can see her hair under the turban.
Factual error: A 1955 Chevrolet is parked in front of Lily Tomlin's 1955 Dodge. Its license plate reads "528 GPR." California license plates did not begin to use combinations of three numbers followed by three letters until 1969. The "528 GPR" plate would have been issued circa 1975 and originally had yellow letters on a blue background. For the movie, the blue background was repainted black so the colors were appropriate for 1955. However, an actual 1955 plate would have three letters followed by three numbers.
Character mistake: The girl scores a goal in the soccer game but it does not actually go into the goal, so everyone is celebrating a miss. (00:02:00)
Factual error: The timeline is completely wrong. The film begins in 1902, at which point Gertrude Bell has just left Oxford and is about to go to Persia. In fact, Bell was 34 in 1902 and went to Persia ten years earlier, in 1892. By 1902 she had already been travelling for a decade.
Continuity mistake: As Sean Penn arrives in the bar at the beginning of the movie, Annie is engaged in conversation with another man, saying "We have to meet the new Minister of Health." You can spot her in the group shot and she has her elbow on the table and leaning her head against the hand. In the close-up her position is completely different. (00:03:00)
Continuity mistake: When Sienna Miller says "sorry" after dropping the bottle of champagne from her apartment on a naked Tom Hiddleston, in the faraway shot she is holding her glass in hand, but in close-up she is chuckling with the free hand in front of her mouth. (00:05:05)
Continuity mistake: The blood on the good guy's white shirt continuously changes through the last chase. (01:22:00 - 01:26:00)
Continuity mistake: In the scene with the fireworks, the Deputy driving the vehicle has his outside mirror knocked off by a firework. You then see the same and only Deputy in the car, in the mirror getting out of the passenger side of the vehicle to confront the misfits. The change isn't due to the reflected image. (00:13:05)
Factual error: In the football match between Dungatar and Winyerp you can occasionally see the railway line in the background. This is the Melbourne to Adelaide rail line in use today. The rail line has concrete sleepers, which were not introduced until the 1980's. They can be seen as they are whiteish. The Dressmaker is set in 1951.
Other mistake: The day before the business trip, Vince Vaughn enters his son's room. They have an awkward chat about masturbation and when he leaves, his son checks out of the bad things that bullies with even worse photoshop skills post on Facebook. He is looking at two different posts, but two comments are exactly the same in both, complete with the same peculiar spelling mistake. (00:08:30)
Factual error: Ships depicted in the film have steering wheels, which would appear several decades after the events depicted. Steering wheels started to be implemented on vessels at the beginning of the 18th century.
Continuity mistake: When Zipper drops her off at her car at the beach, Marnie is wearing boots when she gets off his motorcycle. When she walks to the car she's wearing shoes.
Continuity mistake: When Penelope is sunbathing whilst Paul is on his laptop, she is face down with her head touching the lounger, but in the next shot, her head is suddenly raised above the lounger, then back to leaning against the lounger in the next shot.
Continuity mistake: At the beginning of the movie, the first thug is trying to convince Brennan to handle the gun. He repeatedly uses the trigger to show him that the gun is harmless; in the next shot the weapon mid-sentence is already turned around the other way, held out for Brennan. (00:01:15)
Factual error: In the end credits, when the listing of songs used in the film is rolling, the Kiss song is listed as "Detroit City Rock." Actually, the song title is "Detroit Rock City." (01:38:10)
