Character mistake: One of the top most taboo things for a super hero to do is reveal any aspect of another hero's identity to someone, especially a villain. But when Flash is trapped by the gray adhesive and the other Justice League members are about to take the villains away to disarm the bombs, Flash tells Green Lantern "Hal, go", calling Green Lantern by his first name right in front of Mirror Master.

Character mistake: When Sheriff Flemings arrives at the gas station murder scene, Deputy Baldridge is already there taking photographs. The pair exchange a few words and Baldridge says he can't find the victims body. The pair then look up to see three of the flying monkeys noisily eating Mr Sites corpse on the roof of the gas station. Apparently Baldridge didn't notice this the whole time he was there. (01:03:19)
