Light Years was released in 1988 & blew me away & still does. The original version was directed by René Laloux, and was based on Jean-Pierre Andrevon's novel Les Hommes-machines contre Gandahar (The Machine-Men versus Gandahar).

A certain scene in the English version was edited due to sexuality – the scene where Airelle and Sylvain are in the nest. In the uncut version, Sylvain is shown removing his shirt, later, he and Airelle are shown lying nude in the nest at night, seemingly after having been intimate with one another.
A quick search will turn up the film in parts on youtube
