I'll reserve judgment untiil I learn more. People in the movie inustry have a tendency to totally change pretty much everything in a movie based on a book, or in this case a trilogy, which may be wose. Can you imagine trying to pare down those three books into a single movie?
I doubt very much they could, without reducing
Foundation and the first half of
Foundation and Empire to a mere prologue.
I'm skeptical that they could do even
Foundation as movie as
Foundation is essentially a collection of linked short stories, that cover a timespan of decades, which were originally published in magazines.
I'd definitately see a movie, but I feel a better way to present the Foundation series would be for a Sci-Fi Channel miniseries ala Dune.
