Artist and author Ron Miller worked on David Lynch's 1984 film Dune as a concept artist. Last week, he wrote about his time on the film in honor of its 30th anniversary, slipping in a defense of the often derided final product for good measure. He also revealed a few pre-production pictures that proved so popular he came back a few days later to post a whole slew of them, from sketches to production paintings to models to costumes. Dune divided critics when it was first released and continues to be debated among fans today, but few doubt its visual ambition. Much of that ambition can be traced to Miller's work. Sample some of his concept art below and check out the complete gallery here.
