Corrected entry: A conservative estimate of the acid-filled vault's weight is about 4 tons, most likely much more (a previous corrector suggested it was a special light-weight safe that Two-face installed. You can tell from Batman's difficulty in lifting the door that it is solid metal). The strongest industrial cable would need to be at least 1/2 inch thick to hold the weight, even more considering it would have to withstand the additional force as the vault makes its downward arc. The 1/8 inch thick cable that Batman uses would have snapped like a thread under the weight, no matter what it was composed of.
Corrected entry: It's hard to believe that a spontaneous act of throwing acid on Dent's face by the mobster would result in a perfectly even separation down the exact middle of his face. Even with the folder protecting one half, the chances of the acid falling so perfectly seems remote.
Corrected entry: At the end of the movie, as Batman plummets to save Robin, the ropes around Robin's wrists change length! At first they're short and his wrists are within just a few inches of each other, and then the ropes are much longer, long enough in fact to allow him to swing his hands under his feet and above his head with no problem!
Corrected entry: When the security guard and Batman are in the vault, the "boiling acid" begins to fill the bottom of the vault. The vault is currently being suspended vertically with the door on top. After Batman saves the day and returns the vault to its original horizontal position, there is no acid spilling out of the door of the vault. (00:08:20)
Corrected entry: After Edward lets Stickley fall from the window and is walking back to his desk, the cord that was attached to the "box" headpiece is missing.
Corrected entry: Near the beginning of the film, during the chopper sequence, Two-Face jams the controls with a Club. First off, what's that doing there aside from product placement? Also, Batman doesn't have anything that can remove/cut/pick it? (especially since he cut a presumably steel chain earlier).
Corrected entry: When the Riddler and Two-Face show up at Bruce's mansion to abduct Chase, all that the Riddler has with him is his cane and a bag of bat-bombs. Yet later on, when Two-Face is about to kill Bruce, the Riddler shows up and he suddenly has a box in his hand (the 5th Riddle); where did it come from? He didn't bring it in with him, and he couldn't have thrown it together while he was there.
Corrected entry: When Bruce Wayne is recounting his second flashback to Chase, you see the young Wayne walking up to the red diary and the pages are blowing. When he reaches out and turns the diary, the hand is not that of a young child but the hand of a much older person - you can tell by the wrinkles and roughness in the skin. (01:26:00)
Corrected entry: Near the beginning, when Batman is suspended over the crowd on top of the bank vault, he fires a cable to the bank building itself. The force of the hook causes it to burst through the wall, which looks rather thin and weak, yet he then proceeds to cut the wire holding the vault to the helicopter, causing the vault to swing on the wire he fired through the weak wall. The wall has suddenly become much stronger, and the vault swings back to its original location.
Corrected entry: Batman enters the Riddler's throne room through a small hole in the floor, and it closes after he enters. Then the Riddler introduces Chase and Robin, and two holes like the one before appear under each tube. Nygma says Batman can't save them both. BUT, when Batman jumps to save them both, half the floor has disappeared! Why are Chase and Robin's holes connected, if the Riddler planned not to let Batman save them both? And where did the big big hole came from? It can't be due to the explosions - it's a nice neat line all the way around. The Riddler hasn't pressed the button on his cane yet either.
