Revealing mistake: Before Derek punches the side of the wall, you can see the weakened area of the wall before impact. Look at the color difference.
Continuity mistake: In the first scene, Duncan is sitting to the right side (if we are looking at him) of the back seat of the station wagon. When they are taking the luggage out of the car, there are now bags piled up in the seat on the right side.
Suggested correction: Absolutely no telling how much time has passed between the two scenes. With them being on a road trip, they could have stopped for gas, food, bathroom breaks etc and moved the bags around at any time. Even Duncan could have just done it by himself mid-transit to make a little more room on the floor for his feet.
Factual error: After the scene where Karen Mok is standing in the empty fighting arena, there is a cut to the city night skyline, with the Moon rising fast as time is fast forwarded. However, all the stars remain stationary... Which is nonsense, because the Moon is revolving around Earth much slower than Earth's own rotation. The Moon's (and the Sun's, obviously) rising and setting is because of the latter, that's why the stars should also be moving along with the Moon. (01:10:15)
Character mistake: Luca calls Eve in the dark outside the house, searching her. But they all know that Eve is deaf. (00:33:20)
Continuity mistake: The movie opens with a man walking with a dog by a body of water. He is holding the leash with his left hand and the dog is by his left side. Cut to the next shot taken from across the water, the leash is now in his right hand and the dog is on his right. (00:00:20)
Other mistake: Throughout the film, you can frequently see many people's faces blurred, phone numbers blurred, store-fronts blurred, etc. This is because the production could not afford the rights to show these people, places and things, and simply blurred them out.
Continuity mistake: Having just reached New York, Langston tries to reach by public phone Reverend Cornell Cobbs. The receiver is in his right hand, until there's a cut to the reverse angle and the phone switches to his left hand. (00:12:30)
Continuity mistake: After he finds the dog and goes back to crank the battery, it only charges for 1 min 36 sec. But after he names the dog Sherlock, he cranks again and the time that shows behind him is 1 min 42. (01:01:30 - 01:05:30)
Factual error: When Diana's father's surgeon shows Diana around the hospital, they end up in an operating room and they are both wearing street clothes. Problem is there are doors in every hospital where operations are performed and no-one is allowed past those doors without wearing scrubs, paper hats, booties and face masks, no matter who you are - they have to keep the operating rooms as clean as possible.
Factual error: Dido and her husband had 3 children, not two as stated at the end of the movie. Furthermore, she didn't received an inheritance worth 2,000 pounds a year from her father.
Continuity mistake: The protagonist is told about the budget cuts that will lead to the library shutting down. During the scene, the strap of his hat keeps going back and forth in front / behind his ear. (00:02:05)
Continuity mistake: The Appraiser puts the condemned tape across Dorothy's wrecked porch. The tape from the bottom right to the upper left is the one in the front of the other diagonal line, but then it's the other way around. (00:07:30)
Continuity mistake: In "China", when the trackers and the hunters are walking through the forest at night, between shots, the group goes from five people to four people back to five people. (00:30:46)
Continuity mistake: After the fake movie intro, the two guys drive to a secluded place where their drop is supposed to happen. "Cheno", the one in the driver seat, has the right hand down his side and the left hand on the right side of the steering wheel in a pretty unique position. But in the reverse shot, it's his right hand on the wheel. (00:03:00)
Factual error: Near the end, Zoe and Trey battle to the death, Zoe armed with a tomahawk and a knife, Trey armed with a Husqvarna chainsaw. During the battle, Zoe manages to amputate Trey's right hand, with which he was gripping the chainsaw's safety release and trigger (as his left hand gripped the support handle). Bellowing in pain, Trey continues swinging the chainsaw by its support handle with his left hand. Lo and behold, the chainsaw is somehow, miraculously, still revving in-and-out, which is only possible if the safety release is continuously depressed with the palm of the right hand as the fingers rhythmically flex to squeeze the trigger. Of course, with all major tendons in the wrist severed, an amputated hand cannot grip or flex or squeeze anything.
Continuity mistake: Max is wearing a suit jacket while he is beating a young woman. He throws her against a dresser and then when he goes to pick her up he is in shirtsleeves.
Factual error: The movie takes place in Carolina Beach, N.C. (east coast), and yet a number of times the protagonist, and others, sit on the beach and watch the sun setting over the ocean.
Continuity mistake: When Turbo is about to go down the curb after nearly getting killed by the lawn mower, you see him lined with the 2, he's on the left side of the 3.
Deliberate mistake: The whole premise of the movie is 'artistic license' so to speak; the protagonist signs himself up to the bone marrow donors register, called ADMO in his country (Italy). But he is still a minor, and that is strictly not allowed. Not even with a written consent of the parents as shown in the movie.
Continuity mistake: Bera and Bea have multiple sequences where he complains about his roomie Ugo who lashed back at him after all the abuse he had to take from him. There's a plastic cup on the flush tank; in one of the scenes, in between others, the cup is suddenly in a different spot on the tank (more to the right) and the straw is tilted the opposite way than before.
