Factual error: When Nuclear Man takes the publisher of the newspaper out into space. Humans cannot breathe in outer space. Even if they could, wouldn't she burn up in re-entry? It can't be Superman's powers are transferred to someone he's touching, otherwise in the second film he could never have crushed General Zod's hand...
Factual error: When the villain takes the reporter into space (the earth is just a circle off in the distance), then weakens and lets go of her, not only does she start to fall, she starts to fall straight down and has to hang onto him. (Oddly enough, he's not falling). Did somebody inject normal earth gravity into mid-space?
