Avatar may have been his "most personal film to date" (as he says) but part of that may well have been having very personal connections in the early seventies to the Yes album art of Roger Dean, who is now suing for copyright infringement. How hard would it have been to get Dean involved from the start in any case?
This is the art from the cover of An Evening of Yes Music Plus for instance. Erm...
And the whole theme of a fragile planet. One assumes he dug Olias of Sunhillow, Jon Anderson's solo album based on Dean's paintings. For heaven's sake.
Roger I'll be happy to testify mate if you are reading this. Thank you Gerry Canavan for this. Fairly shortly my essay on Avatar will be published (thanks again Gerry) in which the resemblance (more than that even) is noted. And there's this.
