The original draft of the script, by David Howard, was called Captain Starshine, which evolved, over subsequent revisions by Robert Gordon, into Galaxy Quest. The comedic premise is somewhat ingenious: The cast of a once-popular Star Trek-like show, years into their has-been fame of opening car dealerships and fan conventions, find themselves beamed up into an actual galactic battle to save a benevolent alien race. Can they summon the courage – not to mention recall the technical mumbo-jumbo – that was once just play-acting? The film came out more than a decade after William Shatner parodied Trekkie conventioneers on Saturday Night Live. But in Galaxy Quest, which blended real sci-fi with comedy, the actors find their better selves believing in their roles like never before, with help from the sci-fi geeks back on Earth.
