As I and others on this Bard ave mentioned many times, the Ellison screenplay (I never heard that he collaborated with Asimov, although Asimov wroe the original, and apparently approved of the screenplay) has been published in an illustrated edition. I’ve read it – it tells the story without being episodic and without flashbacks or narration. That is a neat trick, but Ellison can be a helluva screenwriter. It’s just too damned bad that, now that they’ve got CGI, they didn’t film that creenplay.
I’ve noticed a lot of this – there’s too much “dumbing down” of science fiction ideas in the movies. God forbid somebody should have to think.
