Smack in the Middle (2) - S1-E2
Continuity mistake: Molly is about to disguise herself as Robin. But the wig she's holding isn't even remotely the same color as Robin's hair. Of course, as soon as she puts it on and transforms herself, the wig darkens and becomes Robin's actual hair. (00:05:45)

Continuity mistake: Just after the Joker tells the fake Robin to turn on her homing beacon, a quick shot of the Batmobile approaching shows it isn't glossy black with cherise red trim as normal, but is instead flat black with white trim. This footage was from pre-series testing, painting the car different ways to see how it would look best on film, but somehow this footage was actually used in the episode by mistake. (00:06:20)
Smack in the Middle (2) - S1-E2
Continuity mistake: When Fake Robin takes Riddler's wheel to drive, the shot cuts to the Batmobile. It appears that Robin is a passenger, but he is supposed to be Riddler's prison service.

Continuity mistake: During the fight, the breather Batman has disappears, but suddenly returns afterwards. (00:21:50)
Smack in the Middle (2) - S1-E2
Continuity mistake: After the Garbo joke, the various extras begin to pass out from the gas with multiple inconsistencies between shots. In the shot that follows the joke, the woman with the red and black dress is fainting, but she's back up in the next, in which the policeman goes down, only to be up in the one later, etc. (00:19:35)
Smack in the Middle (2) - S1-E2
Continuity mistake: Riddler wakes Robin up, and the Boy Wonder does not waste time in his tongue lashing. During the scene, the lighting on set is very noticeably different; with the camera positioned between the two, Frank Gorshin's jaw casts a shadow; with the camera behind Burt Ward, it's him casting a big shadow on the green unitard. (00:03:40)
Smack in the Middle (2) - S1-E2
Continuity mistake: Riddler sedates again Robin with the "B" spray. He puts his own mask back on, and on the table the spray can is turned with the letter facing away from the camera. Riddler takes a peek at the unconscious Robin, and in the next shot both sprays have their letters properly showing, only to be hidden again when the same camera angle as before is used again. (00:05:55)
Smack in the Middle (2) - S1-E2
Continuity mistake: Batman, after losing his breather between an "Urkkk!" and a "Zok!" chases down a goon that is making a run for it going for the window. Two other minions are following Batman, but their motion repeats in the next shot, when it's "Zzzzzwap!" time. (00:22:00)
Smack in the Middle (2) - S1-E2
Continuity mistake: Elephant-man Riddler is the one man left standing in the room. The problem is, he is standing with one hand on his hip, which becomes a totally different pose at the cut, with the arm chest-high and his finger pointing down. (00:19:55)
Smack in the Middle (2) - S1-E2
Continuity mistake: During the bait pursuit, Riddler tells Molly-Robin to hold the wheel for him as he puts his helmet on. The Batmobile in pursuit is featured in recycled footage, since both Batman and Robin are in it. (00:08:10)
Smack in the Middle (2) - S1-E2
Continuity mistake: Riddler stares at Batman and Robin popping out of the stuffed animal; in the wide shot he has a (delayed, really) reaction opening up his hand, which becomes a closed fist in the next angle. (00:20:50)
Smack in the Middle (2) - S1-E2
Continuity mistake: The Prime Minister is talking about the stuffing of the mammoth; in the wide shot a couple is approaching, turning round the beast. In the closer angle, they are already behind him. (00:17:10)
Smack in the Middle (2) - S1-E2
Continuity mistake: After wu-xia style jump on the Batmobile reactor, Batman tells the girl "Wait, Molly." In the close-up there's no rope, but before and after there's still the batarang rope visible by him. (00:11:35)
Smack in the Middle (2) - S1-E2
Continuity mistake: Riddler just sent Molly to make the mask. As he sprays Robin, the strap across his chest is fastened in a different way in the close-up. (00:03:20)
Smack in the Middle (2) - S1-E2
Continuity mistake: When Riddler emerges from the ventilation system, the grate is placed against the hole. In the rest of the scene it disappears. (00:18:50)
Smack in the Middle (2) - S1-E2
Continuity mistake: After Riddler bursts through the vent, the position and arm movements of Aunt Harriet are inconsistent between shots. (00:18:45)
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.
