Plot hole: When there is a big explosion at a plant and Superman flies in to save the day, all he does to stop the explosions is pull down the toggle of a huge switch situated on the wall; if this is all that was needed to stop the explosions, then why didn't one of the workers do it, and save Superman the trouble of flying all the way out there to do something which one of the workers could have done easily.
Suggested correction: Listen carefully just before Superman arrives. A worker can be heard saying they can't pull the lever because it's red-hot.
Suggested correction: The toggle was red-hot. Workers couldn't touch it.
