Galaxy Quest Synopsis
They're not astronauts they only played them on TV. For four seasons, from 1979 to 1982, the crew of the NSEA Protector donned their uniforms and set out on thrilling and often dangerous missions in space - then their series was canceled.
The Thermians, a race of aliens, have mistaken intercepted television transmissions of the show for "historical documents." Arriving on earth, they whisk "Commander Peter Quincy Taggart" and his crew into space to help them defeat an all-too-real and very deadly adversary. With no script, no director, and no clue about real space travel, the actors have to turn in the performances of their lives to become the heroes the Thermians believe them to be.
