Corrected entry: Immediately after defeating his 'evil' self, Superman repaired the oil tanker, then flew off to Webster's, then straight off again to the grand canyon for the showdown with the big computer. When the computer starts going haywire, it turns off the lights in the subway train. For a moment before this you can see someone reading a newspaper with the headline: "Superman Super Again". There is no way enough time has passed for this news of Superman to make it to the front page of a newspaper, even if it's an afternoon edition that was rushed to the press. Besides, Superman has performed all of ONE superheroic act, namely fixing the oil tanker, and they are still miles out to sea. So as far as anyone in Metropolis is concerned, Superman is still 'evil'.
Corrected entry: Two former "Our Gang" members appear in the movie. Jackie Cooper (Perry White) appeared in 15 of the shorts in the early 1930s, and Annie Ross (Vera Webster) was in "Our Gang Follies of 1938" when she was known as Annabelle Logan. She was the little girl singing "Loch Lomond".Jeff Swanson
Corrected entry: In the end when Clark is meeting Lana at the hotel in Metropolis and he is giving her the diamond ring he pressed himself from a piece of coal. Then Brad shows up in an attempt to get Lana. How do you expect a drunken security guard (who probably got fired later on) to find out where she is, afford a flying ticket and find the hotel where she is staying?
Corrected entry: When Superman is trapped inside the force-field/bubble fired by the Supercomputer, there is a gaping hole visible, so he shouldn't have any problems breathing whatsoever. Also there are very obvious wires visible suspending the force-field (easiest to see against the computer's structure).
Corrected entry: Towards the end of the movie, when Superman drops Gus off at the coal mine, Gus begins talking with the coal miners about him and Superman. He then rips open his shirt (as if he had a Superman costume on underneath). How did Gus know that Clark Kent tore his shirt like that in order to change into Superman? The only people who know this fact are the ones who have seen the transformation from Clark to Superman, i.e. the audience.
Corrected entry: When Gus is talking to Ross, Vera and Lorelei about how Superman saved the entire Columbia coffee bean plantation, Gus says to Vera, "You didn't see him flying out of the clouds?" Later in the movie when Ross, Vera and Lorelei are using balloons to get down the canyon to reach the supercomputer, Vera asks why he won't balloon down. Gus' response is, "I just don't believe a man can fly."
Corrected entry: When Superman is fighting against Gus Gorman's super computer, it encases Superman inside an air tight rubber-like bubble. Then Vera Webster mentions something about how long Superman can carry on without any air. Superman then starts to panic and knows he must get out. Then why doesn't he ever have any trouble when flying through outer space? There's no air at all there.
Corrected entry: In the scene where Clark Kent attends his High School reunion dance there is a big picture on the wall of him as a teenager. The picture is of a young Christopher Reeve who is not wearing his Clark Kent glasses and so looking exactly the same as Superman. Why did none of those present at the dance make the connection?
Corrected entry: When Superman is in Smallville for Ricky's birthday receiving the key for the city, Gus and Webster's sister show up in a jeep disguised as military people, Gus makes an over-the-top speech and gives Superman the artificial kryptonite. Luckily, it doesn´t kill him or affect him at once, but suppose that it did? What plan did they have to get away from the place after killing Superman right in front of half of Smallville?
