Surf's Up! Joker's Under! - S3-E10
Other mistake: An amazingly precognizant Dick Grayson is already wearing his surfing togs before Commissioner Gordon calls to say that Joker has invaded the surfing community. (00:04:30)
Suggested correction: Dick isn't amazingly precognizant. He's wearing swim trunks while using the rag to prep his own surfboard. Barbara Gordon was already at the beach with Skip, and Dick is heading to the beach with his surfboard as well (00:04:34).
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)
Other mistake: After King Tut's men deliver the statue, it's referred to as a Sphinx. Even Batman says, "Rather good imitation of the 4th Dynasty's Sphinx at Giza." Problem is, the Great Sphinx of Giza is a reclining lion with a human head. The statue in Gotham's park is a ram's head atop a seated human body, resembling Egyptian God Khnum, and looks nothing like the Egyptian Sphinx. Bruce Wayne is a member of Gotham City Museum's Board of Trustees, which recently opened the new exhibit of Egyptian antiquities. (00:10:35)
Fine Feathered Finks (1) - S1-E3
Other mistake: If the camera in the Penguin's cell is hidden and stationary, then the video taken from the cell should all be from the same angle, but not only does much of it move along with the Penguin as he paces, it also is much closer and at a lower angle. It only reverts back to being hidden when he notices it.
The Clock King's Crazy Crimes (1) - S2-E11
Other mistake: When Clock King activates the coils to ensnare Batman and Robin, the coils ensnare Batman first, while Robin just reacts. In the next shot, Robin is tangled as well.
Other mistake: When Tut's henchman slowly reads that Bruce Wayne will donate his talking sphinx to the Black Museum at Scotland Yard from a newspaper, a close-up shows he is reading it upside down.
The Bookworm Turns (1) - S1-E29
Other mistake: When Gordon falls into the water after being shot, the footage is in black and white, vs in color.
True or False-Face (1) - S1-E17
Other mistake: When False Face lifts the wig off Blaze to reveal the crown that is on top of her head, you can see it is not there until the next shot of her.
Hizzonner the Penguin (1) - S2-E17
Other mistake: When Pengy shows up at the Grand Order of Occidental Nighthawks he feigns shock, then as he shoves his umbrella into the vat of sulfuric acid, Penguin moves his arm/hand toward the right to pull out a different umbrella, one that appears destroyed by the acid. (00:22:55)
Other mistake: When Mr. Freeze is moving through the room evaluating the diamonds, the tanks on his back can be fire extinguishers. There is no way that the "weapon" attached by hose to them will work, as the handles have to be squeezed to discharge.
Other mistake: The Joker's escape is so cartoonish and ridiculous you wouldn't even know where to start; besides the fact that the explosion somehow engulfs instantly the whole baseball field, the guard on top of the wall is following his movement with the gun, so he sees the Joker, therefore the smoke screen is useless, not more effective in any way than the mere surprise of a coil suddenly springing up from the ground.
The Penguin's a Jinx (2) - S1-E4
Other mistake: In the pre-credits recap of part 1 of the episode we see Bruce awake and staring in horror (with actually a super hilarious face) at the furnace. It was not part of the previous episode at all and in fact Bruce wakes up only in this second episode.
The Penguin's a Jinx (2) - S1-E4
Other mistake: Penguin is able to follow from his office the unconscious Bruce Wayne on the conveyor belt. Considering the angle and how it keeps perfect close-ups of the moving target, it would mean he has a security camera in the back of his shop that is pointed on the conveyor belt and is mounted on a dolly (and he is not doing anything to control it). Definitely wins him Evil Overlord points. (00:02:40)
Other mistake: At the end of the episode when the cattle are stampeding, the sign over the Saloon is backwards.
The Penguin's a Jinx (2) - S1-E4
Other mistake: Penguin says that his sleeping gas' effect lasts 18 hours, but Bruce in his shop woke after mere minutes (sure, the extreme temperature helped him regain consciousness, but something as potent to knock you out for 18 hours with a small whiff can't completely lose effectiveness just because your feet are getting a little hot). (00:20:15)
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)
Pop Goes the Joker (1) - S2-E57
Other mistake: Not only can Caesar Romero's moustache can be seen, but the line between the white makeup and his skin on his neck. Also, when Robin's face came out of the clay, his mask was almost around his mouth. A moment later, the mask is back in place. Later, his face, mask, and body is spotless.
Dizzonner the Penguin (2) - S2-E18
Other mistake: In the fight in Convention Hall, when the goons surround Batman, watch the one on the front left. He's punching over and down, yet he's hitting nothing.
Dizzonner the Penguin (2) - S2-E18
Other mistake: Batman throws himself into acid. Counting on acid-proof suits, Batman comes out unscathed, but his ropes didn't get burned off until he dipped the back into the acid. Also, even though he covered his face a moment, he came out with his face exposed, and undamaged, when it should have been burned.
The Duo Is Slumming (2) - S2-E32
Other mistake: While Batman and Robin are ascending in the balloon, Robin picks up a chewed piece of gum, and stops the altimeter just before 20,000 feet. After that, Robin wondered how to get down. Beside Batman's head is the handle of the cord that would have started to let the air out, and started dropping them down.
