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.
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.
Corrected entry: If Cobblepot is called the Penguin, then why does he spit and drool ink? He's not a squid!
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.
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.
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.
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.
