Revealing mistake: Towards the ending in the strip club, Locus is getting arrested. When it shows his hands being cuffed, it's not his hands but those of Charles in an earlier scene. You can tell because the person is wearing long red sleeves and a Rolex.
Continuity mistake: As V attacks all of Creedy's men with his knives, in one shot he cuts one man's neck, and blood sprays onto the man's face, but in the next shot as the man falls, his face is clean.
Continuity mistake: Sithandra grabs a branch as she runs through the garden, which changes in appearance between shots.
Continuity mistake: When Jimmy is getting ready to propose, in the shot where he pets his dog, you can see in the first shot from in front he is not moving, yet in the next shot he is walking and leaning towards the dog.
Continuity mistake: When Franks Audi does the big jump from the top of the car park, it lands and you can see the front of the car get damaged, yet in later shots the damage has gone.
Continuity mistake: The plane they are on changes several times throughout the movie. When it is sitting at the gate in Dallas, and while being pushed back from the gate, it is a Boeing 737. When it is shown taxiing out, it is an Airbus A320. Air to air shots are of a Boeing 767, which is also the same as the interior shots all throughout the movie. The 737 and A320 are narrowbodies, while the 767 is a widebody, commonly configured 2-4-2 like the interior in the movie.
Continuity mistake: When Nancy is dancing, she is alternately wearing/not wearing gloves between shots.
Continuity mistake: When Bruce is thrown off the truck when released from prison, you can see his bag in the background as he rolls at least 5 feet away to his right. When the angle changes and he's getting up, the bag is right in front of him, if not slightly to his left. (00:05:50)
Continuity mistake: When the cast are at the Miranda colony and discover that everyone is dead, there is a rotating shot of River as she realises what happened. Prior to this there is a brief closeup shot of the rest of the cast as they turn to face her. Jayne turns to his right, but in the following rotating shot of River he has turned from his left. (01:16:30)
Continuity mistake: The chain saw on the block of ice switches ice blocks more than once.
Continuity mistake: The male lead is seen reading an article in the newspaper, the headline of which says "serial killer arrested at Pendleton University," but when he reads the headline aloud, he mentions the professor that killed students at Alpine University, which doesn't match the headline from the paper he's reading.
Deliberate mistake: When the New York subway is flooded the interior shot shows the station is Wilshire Blvd. Wilshire Blvd is in Los Angeles and the film clip appears to be stock footage from the Universal Studios Tour ride.
Factual error: In the fire at the lighthouse, Stevie puts her hand on the fire extinguisher nozzle. It would have frozen her hand and made it stick to it.
Visible crew/equipment: When Amanda is tangled in all the ropes and straps in the plane you see a diver behind her trying to hide from the camera man.
Visible crew/equipment: When Agent Stone first escapes from jail and he is about to get into the GTO, as he opens the car door you can see a crewmember in the reflection of the car. And as they drive off, you can see the huge reflector screen in the back side of the car. (00:13:40)
Plot hole: In the end, when Charlie is advancing on Emily while turning his light on and off, the final time he turns it on, Kathrine is in front of Emily. How could she get there so fast without being heard? There's at least 4-5 inches of water that would make sneaking very hard.
Continuity mistake: In the scene after the French General attempts to burn down the forest, Jacob throws the magical axe at the King's servant, who is attempting to kill him. The magical axe comes back and kills the servant. In the next scene, you see Jacob climbing the Tower, and on the ground you can see the axe, with no blood on it, and the body is nowhere to be seen.
Visible crew/equipment: When Wendy goes into the bathroom, you can see the cameraman's shadow moving. (00:48:45)
Continuity mistake: When Danny meets Sam the second time he is bleeding on the floor. When he falls to the floor the amount of blood on it differs between the shots. (00:26:55)
Revealing mistake: Towards the end when Harmony calls Perry's phone as she's lying on the ground, Harry grabs the phone and looks at the caller ID to see her name. Unfortunately that's not the display showing who's calling. Anyone who has a Nokia phone will recognise that that's showing the contact list with just two entries - Harmony and a random number. The fact that it says "contacts" at the top of the screen is a bit of a giveaway.
