- Actor Allusion: In the Japanese dub, Akiji Kobayashi, the man who played the original Ultraman's Captain Muramatsu voices this series' team leader, Arthur Grant.
- Recursive Import: While Australia-made and shown briefly on American TV, it was later shown on Japanese airwaves under the title Ultraman Great (which is also the Japanese name for the hero to differentiate him from the original Ultraman).
- Retroactive Recognition: Some of the Japanese dub's voice actors would go on to play other Ultra Series characters, notably Shingo Yanagisawa (voice of Charles Morgan), who later played Officer Shibukawa in Ultraman Orb.
- What Could Have Been: Apparently, there were plans for a Season 2 that would have featured a number of returning monsters, including a reappearance from Ryugulo and the appearances of several monsters from the Japanese shows, such as Baltan.
