Nightflyers

Just for the record, I haven't read the novella this is based on, though I've heard it's much better than this movie. As a movie alone, it's a very fun sci-fi thriller that looks downright incredible. It's some of the best sci-fi movie set design I've seen, and the movie doesn't waste a centimeter. The story is basically about the implications of telekinesis, and uses the Alien "trapped-onboard-a-spaceship-with-malignant-force" set-up to exploit it (with much "sturm und drang"). The film has very well-drawn characters, like the loose-cannon telekinetic (Michael Des Barres), the wistful, elderly professor (John Standing) whose search for the mythical Volkind (itself a pity case from his colleagues) is the reason for the mission, and especially Royd (Michael Preed), whose unique, reclusive existence on the ship offers the main thrust of the story. Highly recommended for fans of sci-fi and obscure cinema.
