Continuity mistake: At the beginning, when Rumor attacks Croc's men, he ties them up and wraps up their mouths (gags them). But in the next shot, none of their mouths are wrapped up.
The Batman (2004)
1 continuity mistake in season 4 - chronological order
Starring: Alastair Duncan, Rino Romano, Evan Sabara
Factual error: In s01e08, "Q and A", when Yelena is playing chess, we see her use the touchscreen which represents the chessboard. However, the bottom left corner is a white square when it should be a dark square. The board is orientated incorrectly, even though the board on the floor isn't.
The Joker: Sorry Batman, but Joker always laughs last.
