Smack in the Middle (2) - S1-E2
Revealing mistake: While Riddler is with the unconscious guests at the Moldavian exhibit, in the basement of the Moldavian Pavilion the Mole Hill gang blow up the ceiling to create an entry to the exhibit, on the floor above. They lean two tall ladders at the side of the hole and climb up. When Riddler makes for an escape Batman follows him down below, and now we can see long metal brackets bolting the ladders to the floor for safety. (00:20:20 - 00:22:00)

Smack in the Middle (2) - S1-E2
Revealing mistake: Batman tosses the Batarang at Riddler after bursting through the door and yelling "Surrender, you rat."

Revealing mistake: Of all the possible mistakes related to the Robin mask Molly supposedly wears, the one that really could have been avoided was the fact that the camera does not cut away from Burt Ward while he is in the middle of the gesture of turning around and 'ripping away the mask', but only after he's done it, so you can tell nothing came off, nothing moves in his hair, let alone the face itself.

Smack in the Middle (2) - S1-E2
Revealing mistake: When Batman bursts out from the mammoth, one of the 'unconscious' extras changes position reacting to the practical effect. (00:20:45)
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.
