Fantastic Planet

...is still beautiful.

I first saw it in NY in '73, when it was released domestically after it won the Jury Prize that year at Cannes. I saw it again in '76. Recently, a "UK Special Edition" was released which has a better anamorphic transfer, a much more in-depth booklet, the ability to disable subtitles and a choice of English (the USA theatrical dub, featuring Barry Bostwick of all people) or the original French.

The Wiki is here.
