The Dune Cast
Patrick Stewart replaced Aldo Ray as Gurney Halleck.
Virginia Madsen replaced Anne Louise Lambert as Irulan.
John Hurt was offered the part of Dr Yueh.
Glenn Close was offered the part of Jessica, but turned it down.
In an article in Entertainment Weekly she said:
"I turned it down [because] there was this scene where they were running away from the big worm or whatever it was and the woman fell down, and everyone had to come back to get her. I said, 'What a cliché. I don't want to be the woman who falls down. I want to be the woman who's running just as fast as everyone else.'"
Helen Shaver also test for the role of Jessica
Tom Cruise, Kevin Costner and Val Kilmer all tested for the part of Paul Atreides.
