The covers of the Eddings books had a vibe I really liked and would look stunning in a movie - the actual stories didn't match very closely though IIRC, though I was a fan back inthe 80's. 

One cover featured a kind of river/waterway/canal thing built up over a forested landscape with a big ship travelling along it...awesome - but not in the actual book.

I'd like to see an SF movie totally devoted to the work of Chris Foss - just grab all his coolest paintings as a starting point and write a story around them, heheh.

Cheers
