If 'Star Trek' is about pointing out the potential that is the clever, hard-working ingenuity of man and a hopeful tomorrow, than Galaxy Quest is about what happens when that idea is applied quite literally. Except, y'know, without all the idealized characters running the show, but actual, flawed individuals with lives that are falling to pieces.
Galaxy Quest is a film that came out at the end of the century and on the cusp of the New Millennium. The year was 1999 and it was a good year to be a Science-Fiction nerd. Why? Because Galaxy Quest, with its star-studded cast and intelligent writing, was meant to be the mocking parody of 'Star Trek' on the grand stage: the silver screen. The film takes place eighteen years after their sci-fi adventure show "Galaxy Quest" is canceled. That means that actors Jason Nesmith (Tim Allen), Gwen DeMarco (Sigourney Weaver), Alexander Dane (Alan Rickman), Tommy Webber (Daryl Mitchell), Fred Kwan (Tony Shaloub) and Crewman #6 (Sam Rockwell) are making appearances at sci-fi conventions and store openings in costume and character. They're wallowing in despair and are constantly at each other's throats--that is until alien visitors known as Thermians arrive and, having mistaken the show for "historical documents" and consequently modeling their entire culture around it, take them into space to save them from the genocidal General Sarris and his armada.
