@Anorack So yes, this is a cash grab piggybacking off Alien (and maybe a bit of Battlestar Galactica), but IMO it's a pretty respectable pulp sci-fi film that transcends its limitations and is enjoyable on its own terms. Sid Haig turns in a respectable performance, Ray Walston is terrific, and the ending is pretty great.
Also, James Cameron (yes, THAT James Cameron) was production designer and second unit director.
And: what an amazing poster.
@MisterBigFart That's a hell of a poster.
