Trivia: Ulysses 31
- International Coproduction: French / Japanese.
- Keep Circulating the Tapes: The complete series has been released in Europe at one point, but not the U.S.. While there was a Region 1 DVD, it only contains four select episodes. Additionally, the series was also available on Jaroo (which has since been discontinued), but it was just those same four episodes. It didn't help that they were identified as episodes "1-4", when in fact they weren't.
- This is quite amusing since in many cases, releases available in America are virtually unavailable anywhere else, Gargoyles being a prime example.
