Continuity mistake: The Moldavian host calls attention on the national treasure before the cake is brought. In the wide shot, just before the cut you can spot the man in white uniform turning his head to his right. In the next shot he is turning towards his left. (00:01:05)
Revealing mistake: Riddler laughing maniacally after handing Batman the lawsuit turns around and leaves, not before tipping a vase over. There is a crashing noise as if the vase shattered, but the vase is tumbling in a full 360°, undamaged. (00:11:50)
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)
Continuity mistake: The cake exploded and the ambassador is on the floor, his back to the tent. In the wide angle shots and in the close-up, the position is quite different; just look at the golden filigree draped over the tent. (00:01:30)
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
Factual error: Nitrous oxide is not flammable. Not to mention, if it were, Riddler would have risked blowing everything up when he shot the gun in the room saturated with it just to give his henchmen the signal.
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
Revealing mistake: When Batman bursts out from the mammoth, one of the 'unconscious' extras changes position reacting to the practical effect. (00:20:45)
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)
Continuity mistake: Alfred is removing the tray from the table, and Dick leans against the fireplace; between shots, Burt Ward is holding the glass at different heights (look at the mantel decorations). (00:12:45)
Other mistake: The photo of Riddler's arrest shown in the news has the same angle as what we saw, which is the polar opposite side of the corridor Riddler's hired photographers came from. (00:10:10 - 00:12:10)
Continuity mistake: When Riddler hands Batman the lawsuit, he is holding the parchment either one or two handed. Robin also goes from being on his knees to standing, head well above Batman's. (00:11:30)
Continuity mistake: Dick waves the lawsuit in front of Bruce telling him it might contain the other 2 clues, prompting a "Great Scott." He is holding it with hist right hand, then the left. (00:13:50)
Continuity mistake: When Robin moves away from the window of the art gallery, the shadow he casts is completely different between shots. (00:09:00)
The Penguin's a Jinx (2) - S1-E4
Visible crew/equipment: As Mr. Jay is talking to Bruce and Dick, on the wall behind Dick you can see the shadow of the boom mic. (00:23:45)
Revealing mistake: As the Batmobile exits the Batcave, if you watch the exit closely, you see the shadow of the back end of the car come to a stop, meaning that it was at the wall of the set. (00:05:10)
Answer: It's wasn't unusual for multiple actors to play one character on this show. The villains on the TV Batman were played by guest stars, not regular cast members. George Sanders, Otto Preminger, and Eli Wallach played the part at various times. They may simply have only wanted to play the part once or twice, or they were later tied up with other projects, making it necessary to cast someone else. Other characters, like Catwoman, were also played by more than one actress.
