New this month Factual error: At the start we see a blind man and his guide dog, who runs off after a smaller dog. Guide dogs are specifically trained not to do this before being given to their owner.
Continuity mistake: When Gus is falling from the building on his skis the sky changes colour from shot to shot.
Visible crew/equipment: When the evil Superman flies into the junkyard, you can plainly see the wires from the harness.
Continuity mistake: When Superman enters the acid storage room we have a glance at the temperature needle and can see it is way to the right; but the chemist is calm and no alerts are active. Minutes later, before the place explodes, while Superman is freezing the lake, the lights in the room turn red and the chemist freaks out, but the needle is further from the danger zone than it was when we first saw it.
