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)
The Riddler: You and your trained, exploding shark.
The Penguin: How was I to know they'd have a can of shark-repellent Batspray handy?

Trivia: The 1966 T.V. Batmobile was created from a decade-old "concept show car" designed and built in 1955 by Ford's Lincoln Division. It was called the Lincoln Futura, and was originally a pearlescent pale green. After several years on the car show rounds (and an appearance in one movie, repainted red), it was sold for $1 to George Barris who stored it outdoors for 6 years. When FOX called looking for Barris to build a car for the show, they gave him 3 weeks, so he grabbed this already-weird looking car he had out back, sketched a few changes and passed the physical work to Bill Cushenberry. It was finished on time and the rest is history.
Question: What city was used for Gotham City?
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.
