FernGully: The Last Rainforest (1992)
"Basically all these movies are just dances with wolves. Fern gully, Atlantis, avatar, the last samurai, pocahontas and quite a few others all follow the same premise. Good guy from bad group gets enmeshed with locals, usually falls for a girl, discovers their magical culture, ends up joining them and defends them from his group."
Rik Mayall was a legend.
I also found out there are deleted scenes, including one were the Horned King's undead army murders his henchmen in a very disturbing and frightful way. The movie's a lot darker than any Disney film I know of.
