Corrected entry: The big question at the end of the film - Does Edward Nygma know who Batman really is? Once they see that Nygma is crazy everyone is confident that Batman's real identity is a secret. Unfortunately, they don't take into account Two-Faces large team of henchmen who stormed Wayne Manor, all of whom (presumably) now know that Bruce Wayne is Batman. Less than half of them were captured by Batman's underwater net, leaving several to spread the word of Bruce Wayne's secret identity.
Corrected entry: How did Bruce Wayne get planning permission to lay miles of metre-wide metallic pipe complete with flourescent lighting, and which presumably needs some sort of regular maintenance, beneath Gotham's busiest streets, skyscrapers, office buildings, traffic spots etc. The logistics involved do not bear thinking about and even if he used city hall connections and called in favours from old friends (which he would certainly be able to do being a billionaire businessman) he would need a bloody good reason to rip up half of Gotham's streets. He obviously didn't say it was so he could get to the batcave quickly so how on earth did he do it without anyone asking awkward questions? Surely just hiding a batsuit and 'spare' batmobile in a vault in the basement of Wayne Enterprises would be easier?
Corrected entry: More curiosity than goof - all throughout the movie, Batman keeps nagging Robin that he should not kill Two-Face - it won't bring back his parents and will make him kill again, and again... But at the end of the movie, Batman has put an ample amount of change in his pockets (utility belt?) just to fool Two-Face to grab for his coin amongst the change, and...well, you know what happened. What kind of example is this for Robin? Surely if he could reach for his change, he could have reached any number of devices from his utility belt to contain, not kill, Two-Face. Also keep in mind that Harvey Dent (who became Two-Face) was a friend of Bruce Wayne, which adds to the coldness of his death.
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)luchador
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.
