Visible crew/equipment: In the town in Texas when General Zod and his crew first visit, watch when the boy's father (elevated by Zod's finger) falls to the ground. You can see the pad under the dirt when he hits it.

Other: Roughly 5-10 minutes from the end, Superman is returning the White House's flag to it's rightful place, flying over the fountain on the lawn...which is frozen solid in place. Obviously a photo backdrop.

Visible crew/equipment: When Superman is fighting Non under the New York Streets (in the sewers),manhole covers start to jet up in the sky. When the first manhole cover shoots up you can quite clearly see the gas tube in the hole and the gas cylinder attached to the cover.

Factual error: After Superman accidentally frees the phantom zone villains with the exploding hydrogen bomb, they start flying towards the moon. The sleeves in their clothes can be seen fluttering around. This would be impossible because there is no air in outer space, hence nothing to cause resistance against the clothes.

Factual error: At the end of the film Superman puts the US flag back onto the Whitehouse. Whilst he is speaking to the President through the hole in the roof the flag can clearly be seen flying in the wind, but his cape is completely still.

Other: In the beginning, when Superman is flying to the Eiffel Tower, the last scene that shows him flying towards the tower, you can see the wire Christopher Reeve was attached to as he swoops down. The wire stretches all the way across as Superman glides down.

Visible crew/equipment: Ursa throws the sewer lid at Superman sending him flying backwards into the car windshield. Watch the sewer lid carefully when Superman actually hits the windshield. You can see that the sewer lid was actually attached to a belt around his waist so that it would stay in place for the shots where he is flying backward through the air.

Visible crew/equipment: In the shot where Zod walks on the lake's water, there is a platform visible just under the water's surface.

Factual error: When Clark and Lois are on their way to the diner, the wide shot of their car driving along looked very familiar. In fact, it was footage used in the first movie, where the car was used as part of Lex Luthor's "real-estate" plan and was run on remote control. If you look closely in part II, no one is driving the car yet you hear Clark say to Lois, "Hey, you seem pretty quiet over there...."

Revealing: When Zod lifts the boy's father with the beam of white energy, watch closely when he raises him up past the telephone pole...he 'clips' right through it, or rather the pole clips through him, as if he is transparent.

Continuity: During the street battle Superman throws Zod into the coke sign but it explodes before he even hits it.

Continuity: Clark and Lois are undercover in a hotel in Niagara Falls investigating a Honeymoon scam. There is a scene where Clark is removing money from his pocket to tip a porter. You can plainly see that some of the money is falling on the ground. In the next scene the porter walks away with his tip and the falling money has disappeared.

Continuity: In Niagara, Clark moves to the left to warn a kid from falling and a woman next to him lowers her camera. In next shot the camera is up and she repeats the previous movement.

Continuity: In the opening scene where the three villains destroy the energy crystal and the lights go dark and the rings descend upon them, the light that surrounds them is shown coming down from the ceiling. But, when the dome opens, the light surrounding them shines up from the floor. (As also seen in Superman: The Movie.)

Revealing: Inside the White House, Non throws a pillar at the soldiers. When it lands on the floor, it starts to move by itself like a puppet, revealing the whole structure was attached to a string.

Other: When the antenna is falling, everyone on the street is shouting, looking up the sky, running wild in desperation. Except for a woman with a pram. She must be deaf and blind not to notice.

Deliberate "mistake": During the fight in Metropolis, General Zod is about to throw a wall part at Superman, it cuts to a street scene with people and there is a keep clear sign reversed, showing the film was flipped for some reason.

Revealing: When Zod says to Ursa to "blow them a kiss my dear" to the helicopter that's firing on them watch as the helicopter is indeed a real military helicopter, then when it loses control it's an obvious model and just before it crashes into the house it's a full size helicopter again but is completely different from the first one that was originally shown.

Revealing: In the first confrontation between Superman and the Zod Squad, Superman gets chased out over the water. In the first two shots in this chase, if you look at the bottom right-hand corner of the screen (at least in the letterboxed version) you can see the wake of the boat that they used to make these two pull-back shots.

Plot hole: After Clark Kent learns about Zod in the diner and after he was beaten up by that guy in the diner, he realizes that he must get his powers back. So, he walks all the way from the diner to the Fortress of Solitude, a distance of several thousand miles. With no food, no water, no transportation, no money, and just a coat, he manages to walk through miles of snow, ice, and freezing cold to get to the Fortress of Solitude. How does he do this? I don't think any human being could pull this off, and at this stage that's just what he is.
