DUNE WIKIより David Lynch worked on the script for six months with Eric Bergen and Christopher De Vore, eventually adapting the movie into two scripts. The team split up after this first attempt because of creative differences. Lynch would continue to work on five more different scripts. Shooting of Dune finally started with the 135 page 6th draft of the script on March 30, 1983. With a budget of over 40 million dollars, Dune required 80 sets built upon 16 sound stages and a total crew of 1700. The rough cut of Dune under completion was over four hours in duration without post production effects, but Lynch's intended cut of the movie as reflected in the seventh and last draft of the script was three hours long.
