Isaac Asimov did
not write
Les Hommes-machines contre Gandahar (
The Men-Machines Against Gandahar, the 1969 novel on which the film was based). That was by Jean-Pierre Andrevon. All Asimov did was adapt the translation into the English script – which isn't a very creative role; they only hired him so that they could put his name on the poster.
Gandahar, the original, French-language film, has been released on DVD with English subtitles in the UK (cat.# EKA40260; it's restored and anamorphic widescreen and so on). It's region-free (so doesn't require a multi-region player) but it is PAL-format, so won't work on
all DVD players and TVs in America and Japan. See here for more info:

Film Music Vol. 5 (cat.# CFY005). One can hear a few tracks from it here:

bande dessiner who designed the look of the film:

Les Enfants de la pluie (
Children of the Rain).
