Fighting aliens is all in a day's work for the cast of famous TV sci-fi show Galaxy Quest - actors pretending to be aliens, that is. Then one day the crew of the starship (who all appear to hate each other off-screen) find their fictional job has suddenly become real - and they have a crisis to deal with many light years from Earth. A clever, laugh-out-loud comedy that makes fun of classic sci-fi shows, but has much more to offer than just jokes about clingy costumes and pointy ears.
