Corrected entry: It would appear that the aiming mechanism on the Batplane could use a bit of fine tuning. During the scene where Batman is flying the plane towards The Joker, he gets Joker in his crosshairs and fires, however, the bullets simply hit the ground on both of Joker's sides in a very theatrical manner instead of hitting the man himself. While this was obviously done for the sake of getting a fantastic visual, there isn't much sense to it.
Corrected entry: When the purple poison gas is being pumped into the art gallery, the waiter falls unconscious before he actually inhales the gas. He simply looks at it, and then faints before the gas actually reaches his mouth or nose.
Corrected entry: When the gangsters come out of the courthouse and Joker throws a feather into one of their necks, there are two policemen standing on the steps behind the dead man. Despite the fact that the crowd reacts to this blatant public assassination the two coppers do absolutely nothing. They don't attempt to apprehend the Joker or hold back the crowd. They don't even look surprised. They just stand there. I know Gotham's cops are ineffectual but come on.
Corrected entry: When Batman is in his plane and stealing the Joker's balloons, he flicks 3 switches to close the claw around the cables. If you look closely, you can see that the red light next to these switches is labelled "volume" - not really anything to do with the claw; and more to do with his stereo.
Corrected entry: Right at the start of the film when the family are being mugged, you see the crook knock the father out with his gun but when he hits the man, he drops the gun and his hand goes out of shot. When he lifts his hand up to point it at the women the gun is back in his hand. This is much easier to see if you watch it in slow motion. (00:01:40)
Corrected entry: In the scene when Vicki is running up the stairs in the bell tower, at the beginning she has white high heels on. In a later shot, a distance up the stairs, she has flats on, then in the shots at the top of the bell tower, she has her high heels back on.
Corrected entry: During Bruce & Vickie's first date, dinner at Wayne Manor, Bruce asks her if she had a hard time finding the house. Vickie had been at a party there a few evenings before with Knox and, in fact, had met Bruce for the first time that evening. Why would he ask her this as though she'd never been there before?
Corrected entry: Near the end of the film, where Vicky and Alfred are talking by the car, you can clearly see the boom mike (it's orange) in the top of the screen, and it stays there throughout the whole scene.
