There’s not a lot of actual Frank Herbert footage floating around online.  The below publicity interview, audio with pictures, hardly remedies that.  It does, though, offer an opportunity to hear Herbert discussing Dune with David Lynch, director of the film version that nowadays seems equally loathed and loved.  I tend to fall into the later camp.  Script-wise, Dune the movie certainly plods, but there’s no denying Lynch’s visual achievement was as fantastic as it was faithful.
