Continuity mistake: When Dent is talking in the hospital after being rescued, the pillow is bloody on his left side (where he was burned) then the pillow is clean again in another shot.
New this month Revealing mistake: The Lamborghini Murcielago that Bruce Wayne drives changes from a real Lambo to a fake one - in the long shot (down an alleyway) showing the Lambo at the end of the street, It's obvious the wheel base is too short and the ride height is too high. It makes no sense why they would use the fake Lambo in this shot, as the car doesn't get damaged until later in the film.
New this month Revealing mistake: During the opening heist, when one of the robbers is suddenly hit by the bus that smashes through the front of the bank, watch closely. The bus comes nowhere close to actually hitting the man.
Continuity mistake: During the interrogation scene, when Batman beats up Joker, Joker's hands are holding Batman's forearms upside down (from underneath). When the frame changes his hands are now on top of Batman's forearms, then it cuts back and his hands are under again.
Visible crew/equipment: During Batman's interrogation of the Joker, when he picks him up and slams him against the wall, for a very brief moment you can see the camera and the cameraman in the reflection of the mirror on the right.
Visible crew/equipment: In opening scene of the aerial view of the building adjacent to the bank, you can see the reflection of the filming helicopter on the left side of the building.
Continuity mistake: During the bank scene, the Joker shoots the bus driver and he falls dead in front of the bus. As the Joker approaches the Bank manager to put the gas can in his mouth, you can still see the body. But after he removes his mask and walks toward the bus, the driver's body is gone.
Continuity mistake: In the interrogation scene, when Joker sits on the floor, in one shot there's cracks all over the wall, but in the next one there is only one crack, and then again it is full of cracks.
Continuity mistake: In the chasing scene where the Peterbilt truck hits a swat van, the truck's right front light is damaged. In the next scene, the light seems to be undamaged and then, damaged again.
Continuity mistake: The Joker fires a rocket-propelled grenade at the Tumbler, sending it crashing end over end. In the final tumble, as it loses the last of its momentum, it's rolling to rest on its roof. The camera angle then changes and it's suddenly regained momentum, rolling again so it lands on its wheels.
Other mistake: The television that Lau used to communicate with the crime lords was a regular set carried in by Lau's operatives and placed on the table (which didn't have a mic or camera on it), and there were no cameras in the room. So how was Lau able to see/hear/interact with the crime lords?
Revealing mistake: In the scene where Batman is taking down the SWAT members to prevent them from harming the wrong people, one of the SWAT guys is lying on the ground and attempts to stand up. The clip for his gun contacts the ground and flexes like a rubber stunt gun would, not a real clip and gun.
Revealing mistake: As Harvey Dent is tied up in the warehouse with the explosive barrels talking to Rachel, if you look in the lower right hand corner of the screen, a green blanket on the floor moves up slightly as Harvey tries to get out of his restraints. It's too far away for Harvey to touch. A person's fingers or hand is also momentarily visible in the previous establishing shot when Dent is regaining consciousness.
Continuity mistake: When Eric Roberts gets in the car with Two-Face, the car seems to go from being parked to going full-speed in a split-second. As he's getting in the car, Roberts is talking to his driver, and just as he sits down, he sees Two-Face, and the background appears to be moving by very quickly behind him. The car wouldn't have had time to even pull away from the curb yet.
Revealing mistake: In the opening sequence, when the robbers are on the zip line, two Chicago Police squad cars (white cars with blue markings), not Gotham PD (blue with white markings) can be seen blocking off Van Buren Street for the filming.
