Corrected entry: In the scene where Selina Kyle is taking the interview to Max Schreck, she drops her glasses. A few minutes later, when she puts on her glasses to look at the stun gun, we see they are broken. Later, right before Max Schrek pushes her out the window, her glasses are fine.
Corrected entry: When Catwoman and Batman have their first fight, Catwoman stabs Batman with her "claws" in the middle of his stomach. But when Batman is in the Batcave and is pulling one of Catwoman's "claws" out, the stab marks are now to the right (his right) of his stomach. (01:01:10)
Correction: She claws him in his right side. Besides, the claws wouldn't penetrate his stomach since it's covered with bulletproof armor.
Corrected entry: When the ice-queen falls to her death, it's a straight fall. When Batman is shot by the police only seconds later he falls from the same spot, yet he falls onto a ledge and slides down, where catwoman is waiting for him.
Correction: Batman does not fall from the same ledge as the Ice princess does. If you look closely (when the Ice princess is being attacked by the bats) you can see behind her, the top of Town Square (I think) and to HER left, a building with almost every room lit. And when Batman falls down the ledge, you can see he is on the lodge with the building that has almost every room lit behind him.
Corrected entry: So much for the Caped Crusader's legendary (and well-established) code against killing: during the fight scene with the Red Triangle Gang, Batman callously hands off a parcel of high explosives to one of the gang members - only for said criminal to be blown to smithereens a second or two later, with nary a flinch from Batman afterwards.
Correction: This isn't a plot hole. He killed someone in the first movie, as well. It's within the movie universe continuity that he kills, just not the comic book continuity.
Corrected entry: In the scene where Selina comes back from the dead, she enters a room to start making her Catwoman costume. As she enters, she smashes the letters "O" and "T" on the neon "Hello There" sign so that it reads "Hell Here". Trouble is, neon signs are made from a continuous hollow glass tube filled with argon gas. If you break just one of those letters, the circuit is broken and the whole sign will go out.
Correction: One problem - the sign is actually smashed, and individual letters actually stay lit. While that was doubtless specially done for the film, it does prove that those signs can be constructed in such a way for the letters to be separate from each other.
Corrected entry: If Cobblepot is called the Penguin, then why does he spit and drool ink? He's not a squid!
Correction: It's not ink. The guy's obviously got some things physically wrong with him, right down to his spit and drool.
From the toxic waste in the lagoon.
Corrected entry: When Bruce Wayne is playing the compact disc of The Penguin's slanders during his mayoral speech, it's not spinning as compact discs usually do when they play.
Correction: The disc is spinning, but since it's blank and has no markings it's very difficult to see.
Corrected entry: When Batman first encounters the Fatman, Batman has a bomb in his hand which he took from one of the Penguins goons. The Fatman punches Batman and then tells Batman to hit him back. When Batman punches him you can see from the angle of the shot that the bomb is not on the Fatman. When Batman smiles and looks down, the shot changes to the Fatman looking down and the bomb is now there.
Correction: This is not a mistake, the fact that you can not see Batman place the bomb on the fat dude is supposed to be demonstrating Batmans uncanny ability to win battles even over huge enemies. I agree the timing isn't possible, but the shot sequence is necessary to add to Batmans mystique.
Corrected entry: At the beginning of the movie, the newsboy is yelling that the paper costs 50 cents. Later in the scene, he says it's 25 cents.
Correction: This is not a mistake. If nobody wants to buy the paper he has to lower the price.
Corrected entry: Referring to the stun gun, the electrical sparks DO NOT arc between the contact posts as they should - Instead, weird-looking sparks shoot up from the unit itself. Electricity can never do this, it will always find the nearest path to ground which is one of the contact posts. This occurs near the beginning when Selena acquires the stun gun and near the end when she uses it on Max and herself.
Correction: This is not a mistake. The clown that Selena takes the stun gun from has altered it to make it more dangerous.
Corrected entry: The Penguin takes over control of the Batmobile, and goes on a spree. He also says some unkind things about Gotham City, which Batman takes the precaution of recording onto a compact disc. However, when he plays the slandering again, it's different from when The Penguin said it the first time.
Correction: Batman could have quite possibly edited the tape/cd.
Corrected entry: When Batman shakes the CD of the Penguin, he gets an effect as if it was a vinyl record - not possible with CDs.
Correction: We all know it's not possible, but that was the point. . .it's called taking artistic license, or humor as some of us know it. . .
Correction: She probably has another pair of glasses to wear.
