The 1957 film
- Retroactive Recognition: Sterling Hayden playing Captain Martin Treleaven will probably make modern audiences think of Brigadier General Jack D. Ripper.
- Seinfeld Is Unfunny: Or, rather, Zero Hour! is funny; it has been noted that, what with Airplane! and all, it's very nearly impossible to watch Zero Hour! with a straight face anymore.
- It's also not as overly melodramatic (and therefore not as silly) as some other Disaster Movies might be, but it gets lumped right in with them anyway. Case in point: Warner Home Video marketed the DVD as part of their "Cult Camp Classic" line of films.
The comic book
- Awesome Moments: Robin #10 had Dick Grayson and Tim Drake teaming up, both as Robin. Tim notes that Dick is a far better physical Robin (an acrobat, remember?) while Tim is far more tech-savvy and a hacker.
- Contested Sequel: To Crisis on Infinite Earths.
- Nightmare Fuel: The time-erasing void.
- Tear Jerker: Green Arrow apparently killing his best friend, Hal Jordan. (He got better.)
- They Wasted a Perfectly Good Plot: DC could have used the series as an opportunity to restore Katar and Shayera's Silver Age history and undo most of the characters' Post-Crisis Dork Age storiesnote . Needless to say, there's a good reason Hawkman's the image for Continuity Snarl—and this is partly why.
