Continuity mistake: Before the truck is about to fall off the bridge, the blue car in the water moves from a 5 o'clock direction, to a 3 o'clock depending on the shot.
Continuity mistake: While Superman is grabbing the steel chimney, the worker in the far left is seen hurrying to the right to meet his pals. In the next shot he is repeating the movement again.
Continuity mistake: When Superman is about to tilt the Leaning Tower of Pisa, he places his hand with the thumb up. A frame later it's down.
Continuity mistake: When bad Superman punches Clark, he lands half a meter behind a red car hood. In the following shot the hood is by his side.
Continuity mistake: When the Olympic marathon runner holds the torch while running on the track toward the stairs, he has a large upper body build. Also, his shirt has a very noticeable logo that is lying right on his sternum. As he climbs the stairs we see him from behind and this is the last of the real footage from the Olympics. The actor holding the torch, that gets blown out, does not climb the stairs near as gracefully as the Olympic athlete. When they show him from the front, not only does he have very little upper body muscle, but his face is nowhere near the same as the athlete in the stock footage. (01:12:10)
Continuity mistake: After Evil Superman was done melting the mirror in the bar he slowly stood up from the stool to leave the place. The immediate next shot from the sidewalk right outside the bar shows a pedestrian approaching, and as he walks by the establishment Superman can be seen through the window still sitting down at the counter.
Answer: The only reason that Gus was working with Ross, Vera and Lorelei was because he stole money from the company he worked at. To avoid going to prison, Gus was forced to do anything that they wanted. After realizing that his computer was designed to do anything it was ordered to, including killing Superman, Gus removed a small screw which shut down the power momentarily but, after the computer brought itself back online, Gus attempted to destroy it with an axe to save Superman. Superman saw this and realised he was wrong about Gus and after the computer was destroyed decided to help Gus find a job.
That makes sense, thank you! Been bugging me for years.
