Trivia: Ultra Q
- Hey, It's That Guy!
- Kenji Sahara as Jun Manjome; he would reprise this role 44 years later in The Super 8 Ultra Brothers.
- Hiroko Sakurai as Yuriko.
- Haruo Nakajima (the original Godzilla) played a few kaiju in the series.
- Prop Recycling: Many of the kaiju suits. And not all were recycled from this series. The first monster, Gomess, was quite clearly a repurposed Godzilla suit.
- What Could Have Been: Ultraman was originally going to be in an Ultra Q episode, where he was going to be an alien villain, instead of a superhero.
