Other mistake: The opening scene and dialogue with Bruce and Dick responding to Gordon's call is from The Curse of Tut.
He Meets His Match, the Grisly Ghoul (2) - S1-E16
Other mistake: During the opening scene, right after Cesar Romero's guest star, Joker and Susie's faces freeze for a moment.
Batman Stands Pat (2) - S1-E14
Other mistake: When Batman drop-kicks Mad Hatter into the vat of acid at the end of the fight, he does not have even one burn mark when he was pulled out.
The Minstrel's Shakedown (1) - S2-E5
Plot hole: When Batman and Robin explain to the board members at the stock exchange that Minstrel will not be a threat because they dealt with Penguin, Archer, Clock King, King Tut, and Catwoman, in broadcast order, there is a 6-episode difference between Minstrel and Clock King who has never been seen before. To the first-time viewer, they were probably wondering who Clock King is.
Shoot a Crooked Arrow (1) - S2-E1
Continuity mistake: When Batman and Robin are ensnared by Archer's net, Batman says he will get his batknife to free them. When Archer shoots them down with the arrow, they are apparently unconscious but with no explanation of what knocked them out while stuck in the net.
Other mistake: During the final fight scene between the SOCK and POW, Mr. Freeze can be seen in the 76-degree heated section.
Other mistake: While Batman and Robin are pursuing False Face, they stop the Batmobile beside a fence (across from "Bioscope"), and a sign that states "No Trespassing, Desilu Studios" (the show's studio location) is mounted on that fence. (00:15:00)
Continuity mistake: Everytime the Joker is shown on TV his hair is brown, but before and after the broadcasts, it's his usual green with no time for him to change it.
Catwoman Goes to College (1) - S2-E49
Continuity mistake: When they first go to the bat poles, Bruce is on the right. The next shot at the bottom, Bruce/Batman is on the left and Dick/Robin is on the left. They switched sides. It has happened throughout the series.
The Sandman Cometh (1) - S2-E33
Continuity mistake: When Dick and Bruce go "to the bat poles" Dick is on the left side and Bruce on the right. When they get to the bottom, they have switched poles. Dick is on the right and Bruce is on the left.
Penguin's Clean Sweep - S3-E20
Revealing mistake: In any of the close up shots of Penguin, his nose has a completely different skin colour than the rest of his face. Making it very obvious that the actor is wearing a fake nose.
While Gotham City Burns (2) - S1-E30
Other mistake: When Batman realises what needs to be done, the camera turns to Robin with a sixty second clock on screen. Supposedly, Batman did all his actions within sixty seconds to save Robin. Robin was saved after two minutes and three seconds.
The Joker's Provokers (2) - S2-E22
Factual error: During the fight to regain his box, the Joker picks up an orange colored deep well drill bit to hit Batman. First, such a device has sufficient weight that one regular man couldn't lift it easily, let alone swing it. Second, the drill bit wouldn't be lying around in the water works guard office.
Audio problem: When the camera shows the flames of the exhaust, the accompanying sound is wrong. The turbine starting up was played when the flames were seen, instead of the roaring sound effect.
The Joker's Flying Saucer - S3-E24
Plot hole: A time bomb is placed under the dashboard of the Batmobile and goes off inside the batcave. Much of the batcave is ruined, including fallen I-Beams, but the Batmobile has no damage to it even though the bomb was planted in it.
The Joker's Flying Saucer - S3-E24
Other mistake: Just before the final fight scene, Alfred hits his head on the door of the spacecraft while exiting, kind of like the Storm Trooper in Star Wars, reacts for a second and then keeps going on with the scene as if nothing happened.
Answer: There wasn't one singular city used. It was shot in and around various locations in California, plus on a lot of sets and backlots. Ex. Some scenes were shot in LA, some in Pasadena, some in Santa Barbara, etc.
