It deserves to be forgotten.
I don't read the book on which this film is based, I've never seen it for sale, I have doubts if it will exist in Portuguese bookstores. I'm not particularly fond of fiction set in space, but I recognize the quality when I see it. And I didn't see any quality in this film.
The script is totally idiotic: we have an evil galactic empire (someone has been watching “Star Wars” too much), ruled by a tyrant (really original) and a war of resistance in which there is a hero fighting for democracy and freedom on a sandy and inhospitable planet. The problem is that this planet is the only one where it is possible to cultivate a kind of hallucinogenic drug that is vital in the economy and functioning of that empire.
Films directed by David Lynch are not to everyone's taste, and although I liked what he did in other works ("Blue Velvet" and "Mulholland Dr." are, for me, the director's best works), I don't think he was cut out for making sci-fi movies. He has a very visual and stylized style as a director, and mixing that with special effects, a bizarre setting and an even stranger story was a bad marriage. I also have my doubts regarding the collaboration of Dino de Laurentiis… with very rare exceptions, I didn't really like the films in which this director was involved… at least the ones I've seen so far.
Even so, I have no doubt that the potential of the project and the union of efforts of these two names allowed access to a good budget and attracted actors to the cast. However, Lynch doesn't seem comfortable with the material and, aside from some very visual scenes where his signature is present, he doesn't give us much more and isn't able to direct the cast in the best way. I think the director himself is aware of this. Moreover, the weak critical reception and the bad box office results helped to bury the project, which today is conveniently forgotten.
The cast is, in general, quite weak, especially considering the budget involved and the names of the director and producers. Sting, the rock singer, appears in the project, but he's not an actor, and he never gives us a real interpretation: he just says what he needs and shows off. The scene where he appears almost without clothes is, to say the least, idiotic. Patrick Stewart and Max Von Sydow are totally out of the limelight and given minor characters in a movie where they could have possibly done more. Virginia Madsen is ineffective and doesn't convince us, Kyle MacLachlan was a casting mistake, and all other actors settle for mediocrity.
The film has stylized cinematography and many gimmicks, which would have worked better if the film itself weren't already too unrealistic and imaginative. The visual and special effects don't always work well, and the sets and costumes are, to say the least, of questionable taste. The soundtrack is quite epic, but given the general lack of quality, it sounds too pompous for the movie that it is.
