The Clock King Gets Crowned (2) - S2-E12
Factual error: Trapped in the overturned hourglass, Batman and Robin lie flat and begin furiously digging in the sand, making the hourglass roll out the door. But to cause such rapid movement, they'd need to be applying their weight against one of the glass sides (like a hamster in a ball). Just digging in the sand wouldn't get them anywhere, at least not that quickly. (00:04:15)
Other mistake: Riddler says that his "universal wax solvent" can eat through anything. Which begs the question, just what is that vat he cooks the stuff up in made of? We see the wax burn through solid steel vault doors. So it also ought to be eating through the vat, the floor and the bedrock, and sizzling its way down to the Earth's core. (00:07:00)
Hot Off the Griddle (1) - S2-E3
Revealing mistake: During the fight in the museum, one of Catwoman's henchmen slams into the wall beside a window. The set wall buckles and caves in, leaving the bottom edge of the window bent and jutting out. A few shots later, though, both wall and window have repaired themselves. (00:14:00)
The Riddler's False Notion (2) - S1-E32
Continuity mistake: When the Riddler has a blindfolded Robin out on the window ledge, the position of Robin's blindfold changes between shots, from covering his nose entirely to being just above it.
The Joker's Provokers (2) - S2-E22
Factual error: Tsk. After all his lectures to Robin about the importance of education, Batman should and would know better. On the chalk board, where he's written out Joker's message (dictated to him over the phone), the caped crusader mis-punctuates the phrase "a gargoyle's key" by leaving out the apostrophe. Definitely not a mistake that stickler-for-correctness Batman would make. (00:09:30)
The Impractical Joker (1) - S2-E21
Continuity mistake: Toward the end of the fight in the fur salon, one of Joker's henchmen shifts locations instantaneously. In the first shot, he's on the far side of Robin, falling against the wall. In the very next shot, he jumps to a spot between Robin and the camera, where he takes a swing at Batman. (00:17:00)
Shoot a Crooked Arrow (1) - S2-E1
Continuity mistake: When the Archer robs Wayne Manor's safe, an unconscious Dick Grayson shifts positions on the floor between takes. At first, he's lying with both hands folded over his chest. A few shots later, his left arm is stretched out over his head. (00:01:30)
The Joker Trumps an Ace (1) - S1-E25
Continuity mistake: The Joker reveals himself by throwing off his cape, which drops to the floor behind him. But when the shot cuts, the cape instantly disappears. (00:00:50)
A Horse of Another Color (2) - S3-E5
Revealing mistake: Ethel Merman just can't keep a straight face amidst Batman's campy silliness. Here and in the previous episode, she can be seen cracking up in several of her scenes with Burgess Meredith. (00:05:00)
Enter Batgirl, Exit Penguin - S3-E1
Plot hole: When he abducts Alfred, believing him to be a minister, Penguin suffers a peculiar memory lapse. He's encountered Alfred twice before in previous episodes, even kidnapped him once before (knowing full well that he was Bruce Wayne's butler). Yet here, he fails to recognize Alfred at all. (00:12:30)
Scat, Darn Catwoman (2) - S2-E41
Audio problem: At the end, Catwoman falls from the roof into the water below. But we never hear a splash. (00:21:15)
The Zodiac Crimes (1) - S2-E37
Continuity mistake: Joker's floating zap-wand is hanging in the air right in front of Chief O'Hara's face. But when the shot cuts, it's instantly ten feet away, and is now floating behind the Joker. (00:01:45)
The Penguin's Nest (1) - S2-E27
Revealing mistake: When Bruce, Dick and Aunt Harriet get into what's supposed to be an elevator, there's solid concrete under the sliding doors where there should be a break separating the lift car from the building's floor. It's visible again in Part 2, when Batman and Robin use the same elevator. (00:04:30)
The Greatest Mother of Them All (1) - S2-E9
Revealing mistake: When Ma Parker activates her jet-propelled wheelchair, the much younger stunt woman's face is visible as the chair speeds down the hallway toward Batman and Robin. (00:09:15)
Continuity mistake: Batman folds up the Bat Shield and starts to tuck it into his belt, which it is much too large to fit into. In the very next shot, the shield has disappeared. (00:21:00)
Continuity mistake: As Tut prepares to re-animate the scarab beetles, his apothecary henchman stands to his immediate right, close enough to touch his shoulder. But when the shot cuts to a wider angle, the man is standing a foot away. (00:08:45)
Nora Clavicle and the Ladies' Crime Club - S3-E19
Revealing mistake: Not only does Batman's solo flute play two music tracks at once, it also keeps on playing after he's taken it out of his mouth. (00:20:00)
It's the Way You Play the Game (2) - S2-E26
Visible crew/equipment: When Batman and Robin visit Laughing Leo's Used Car Lot, the side of the Batmobile reflects a whole row of big square studio lighting panels. (00:06:30)
It's the Way You Play the Game (2) - S2-E26
Visible crew/equipment: The Batmobile has just pulled away, and as Andy waves good-bye, the camera shadow can be seen moving rapidly offscreen at the lower lefthand corner of the frame. (00:04:25)
Factual error: King Tut is said here to have been a 4th Dynasty ruler. Just as in the previous Tut episode, Egyptian history seems to have entirely escaped Batman's writers. They previously mis-identified Tut's namesake as a 14th Dynasty ruler, and this time around, guessed wrong again. In fact, Tutenkamen's brief rule was part of the 18th Dynasty. (00:03:30)
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.
