Galaxy Quest

Twenty years after its cancellation, the sci-fi series Galaxy Quest continues to inspire a cult following, keeping its faded stars in work with a series of convention appearances. Fans flock to meet their heroes: brave Commander Taggart, curvaceous Tawny Madison and half-reptile Dr Lazarus. But one set of fans have a more pressing agenda - Mathesar and his friends are aliens who have been monitoring Earth media and are convinced that Galaxy Quest is a documentary not fiction and want the crew to help them!
