Character mistake: During the fight in the double deuce where Wesley brings Jimmy in to take all the bouncers on, Jimmy takes on Wade, and Dalton comes to his rescue. Afterwards Wade says to Dalton 'same town new story', when in fact the line should have been, 'new town same story'.
Character mistake: The newspaper that reveals the combination of products that activates the Joker's poison has at least two grammar mistakes on the front page. The word "deodorant's" should not have had an apostrophe, and the word odoreaters was spelled "odoureaters," which has the British spelling of the word odor (Gotham City is obviously in the United States, not the UK).
