- Alternate Character Interpretation: It is not clear exactly how much Ross buys into Loreli's airhead act. Most of the time he seems entirely fooled but in one scene she winks at him while Vera isn't looking, suggesting it might be a game the two are playing.
- Big-Lipped Alligator Moment:
- The scene where the two traffic sign 'walk' and 'don't walk' figures fight each other. It's weird, bizarre, and nonsensical even in this context, and isn't mentioned again.
- The slapstick opening sequence doesn't belong with the rest of the movie, as if the reels were switched with one from a Police Academy movie.
- Colbert Bump: Odds are far more people are familiar with the film these days due to Office Space tacitly admitting it was ripping off the "sending fractions of cents into a separate account" scheme from it than from actually watching the film itself.
- Ensemble Dark Horse: It's probably inevitable that Lana didn't return for the fourth movie, because too much more time spent with her and the audience would have been seriously questioning what Superman ever saw in Lois.
- Fridge Brilliance: It's interesting to see Clark is far less stiff back in Smallville than he is in Metropolis. That's because he's dealing with a girl he knew as a teen, and therefore is more himself around her, even being pixie-ish around Lana. If you wanted to see a midway point between Supes and Clark by Reeve, the picnic scene is it.
- Hilarious in Hindsight:
- Ross Webster was Lex Luthor's replacement as a Corrupt Corporate Executive instead of Mad Scientist. Post-Crisis Lex becomes one himself.
- "You can't run two programs at once". Tech Marches On; your computer is doing it right now.
- A meta example is Annette O'Toole playing Lana Lang here and later playing Martha Kent in Smallville.
- An awkward guy dances to Earth Angel at a prom with his original flame.
- Hollywood Homely: Vera. They make her sound like Quasimodo, but she's a handsome woman.
- Just Here for Godzilla: The only aspect about the movie many fans feel is worth watching is the junkyard fight scene between Clark and Superman.
- Retroactive Recognition: So Lana Lang grew up to become ...Ma Kent! Really, Annette O'Toole played Lana Lang here and (unbeknownst to the producers of the TV show) Martha Kent to Tom Welling's Clark.
- Sequelitis: Usually considered the worst Superman film by fans. Most will concede that Superman IV: The Quest for Peace is worse in technical quality, but will gladly accept its whole-hearted (if very Anvilicious) attempt at a message over this film's broad comedy and Richard Pryor's spotlight stealing antics and, being as loaded with unintentional hilarity as it is, it's easy to argue that Quest for Peace is the funnier movie, too.
- Signature Scene: Clark Kent vs. Superman. It's the one sequence that virtually everyone liked about this movie.
- They Wasted a Perfectly Good Plot: Superman turned evil. COME ON. There was SO much potential there...
- Took the Bad Film Seriously:
- Despite how incredibly stupid the film is the late Christopher Reeve still gives a sincere performance as Superman, both good and bad - which just makes the wasted plot even more offensive.
- Annette O'Toole also gives a pretty sincere effort as Lana Lang. Hell, she's probably more likable as a love interest than Margot Kidder's Lois Lane ever was.
- Richard Pryor also bucked at the idea of playing up Gus to be even goofier, as he wanted to bring at least some gravity to the role, even if it was mainly comic relief.
YMMV / Superman III
