Does anybody even know about this classic from the first reel? Zowie, nerd kids, zowie! What if aliens saw episodes of Star Trek and thought it was the real deal? A great starting point for a sci-fi story. And Sigourney (practically the queen of sci-fi) is not serious, she's playing for comedy, for laughs - a career move bordering on sacriligous (and yet classy as the lady is). A must-see, and perhaps the best Star Trek movie ever!
