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.
  • Science Marches On: Back in 1981, The Solar System was still considered as having nine planets, which are mentioned at some point in the anime. In the 1990s and 2000s, the discovery of several Kuiper Belt Objects that rivaled or exceeded Pluto in size strained the definition of "planet" and reduced that number to eight.
