Trivia: Destroy All Monsters
- Bad Export for You: The ADV release has no menus or chapter stops. That has thankfully been fixed with Media Blasters giving the film a proper Blu-Ray and DVD release.
- Deleted Scene: There is an infamous scene with Godzilla fighting Manda in the middle of the city they are rampaging in. However it was later revealed that the scene was due to Hauro Nakajima and the cast having fun on the set.
- Keep Circulating the Tapes: Media Blasters' DVD and Blu-Ray releases of this movie contained special features that weren't approved by Toho, resulting in said releases going out of print. This has also unfortunately affected Media Blasters' DVD and Blu-Ray releases of Godzilla vs. Megalon as well.
- What Could Have Been: The monster selection of the film was different. Originally, Maguma and Ebirah were to be in the film, and Maguma and Baragon were to act as guardians to the Kilaaks in fending off the SDF. However, due to the frail conditions of the suits owing to constant modifications and use in Ultraman, Anguirus, Gorosaurus, and Minya were substituted instead. Baragon did appear several times in the movie, but Maguma was cut altogether.
- Varan was also supposed to play a larger role, but his suit, like those of Maguma and Baragon, had been overused in Ultraman, and thus, only appeared in two scenes as a motionless plastic model.
