Continuity mistake: When we see Alfred in the Batcave, he had 4 neat piles of playing cards and turns over an Ace. When Batman arrives, there's a shot of the cards, but the Ace is no longer turned over. When he makes the comment about seeing another playing card, the shot changes and there's now 5 piles but not in a neat pile.
Character mistake: Artie says he'll recite pi to 100 decimal places. After the first few numbers, it skips to him finishing up by saying "46375." The last 5 digits would be "70679." In fact, the sequence "46375" doesn't occur until the 95,517th position.
The Penguin: Please, now that all pretenses are off, call me Penguin - a flightless bird, but one with style.
