Character mistake: When the civilians are fleeing the coffee shop, there are two spelling errors on the coffee shop's marquee.

Character mistake: Despite being a Greek mythology buff Maxie Zeus says "Vulcan" when he meant "Hephaestus" the Greek god of fire and the forge when he first spoke with Batman.
