- Disowned Adaptation: Michel Ancel says that the game was "a bit too concrete" for his tastes, and that he would have done the game a bit differently if he wasn't in an advisory role, though he praised the development team and said he was still proud of them. This hasn't prevented the game's events from being mentioned in Rayman Origins, however.
- No Export for You: The game did not get a Japanese release, making it the only mainline Rayman game to have never seen the light of day over there.
- The Other Darrin: Globox is voiced by John Leguizamo in this game, who gives a completely different take compared to Doug Rand's take on him in Rayman 2: The Great Escape and Rayman M, and even the FMV cutscenes. Instead of being deep and slow, he's hyperactive and high pitched. He also speaks in complete sentences, something he was very clearly incapable of in Rayman 2.
- The Other Marty: They were originally going to have Doug Rand reprise Globox but his lines only appeared in the pre-rendered cutscenes. In the actual game, he's voiced by John Leguizamo.
- Screwed by the Lawyers: The most likely reason why "Madder" isn't in the HD rerelease, considering the rights to the song likely belong to Groove Armada, the people who made it.
- What Could Have Been:
- The game had three unique creatures: The Xowar, Glute, and Bonton, who are technically in the game, but in a slightly-difficult-to-reach Easter Egg (get a score of over 43001 points in the Tower of Leptys and a door will open up on your way to the final boss) that only shows them in motion. The Xowar was originally to be a boss and part of a minigame, (though it's possible to see it with a cheat) and the Bonton was to be ridden.
- Additionally, three types of Hoodlums (Gunsliger, Siamese, and Kagoubinome) had not made it in the final version of the game.
- Two mini-games (one involving chess and the aforementioned Xowar) were not in the game at all.
