The film begins at a "Galaxy Quest" convention where the quintet is preparing to appear. Unbeknownst to them, not all of the conventioneers dressed as aliens are pretending. A group of uniformed "aliens" approach Jason (dressed as Commander Taggart) saying that they are in dire need of his assistance. Jason quickly agrees and assumes that the group is planning to pay him to appear as Commander Taggart at a fan-function. Following a night of drinking at his home, the "aliens" arrive in a limousine (per Jason's request) to escort him to their function. The "aliens", calling themselves Thermians, are Mathesar (Enrico Colantoni), Teb (Jed Rees) and Laliari (Missi Pyle). While en route to their function, Teb recites the lengthy history of Thermia to Jason, but Jason (who has a hangover) falls asleep. (Jason doesn't take the Thermians seriously; instead believing that they are simply "Galaxy Quest" fans.) Jason awakens to what he believes is a very elaborate set mimicking the NSEA Protector from the "Galaxy Quest" show. Mathesar (who always refers to Jason as Commander Taggart) tells him that the Thermians want him to negotiate a peace treaty with General Sarris (Robin Sachs). Instead, "Commander Taggart" orders the Thermians to fire upon Sarris' ship. Assuming that he has completed his performance, Jason tells Mathesar that he is ready to return home. Mathesar escorts him to an empty room and leaves. Jason, not understanding what is happening, is suddenly enveloped within a strange substance and raised to the ship's exterior where he sees millions of stars in deep space. He is suddenly shot from the ship, then finds himself standing next to his swimming pool at home. Jason finally realizes that the Thermians are real extraterrestrials, and that they mistakenly regard the "Galaxy Quest" show (which they received in deep space) as being historical fact.

The other four "Galaxy Quest" actors are busy filming a commercial for the opening of an electronics store and are disgusted because Jason isn't there. Jason arrives late and tells them about his experience with the Thermians, but they think he has lost his mind. Jason tells them that the Thermians want him to return and that he wants them to come also. They initially reject it, but change their minds when they mistakenly believe that it's a paying job. Gwen, Alexander, Fred and Tommy are whisked away to the Thermian's NSEA Protector, along with another actor named Guy Fleegman (Sam Rockwell), who had played a bit part on the original "Galaxy Quest" show. With that, the most important role for each of the washed up "Galaxy Quest" actors begins!

Dean Parisot, along with writers David Howard and Robert Gordon, created a brilliant and engaging spoof of the show "Star Trek", its conventions and trekkies with "Galaxy Quest". Tim Allen equated with William Shatner (Kirk), Alan Rickman with Leonard Nimoy (Spock), Sigourney Weaver with Nichelle Nichols (Uhura), Tony Shalhoub with James Doohan (Scotty) and Daryl Mitchell with George Takei (Sulu). Other sci-fi comedy spoof that predate "Galaxy Quest" (such as "Ice Pirates", "Pluto Nash" and "Spaceballs") are no where near as good, engaging or funny.

All of the actors in "Galaxy Quest" performed their roles exceptionally well. Two actor who played significant minor roles were Patrick Breen, who played the Thermian named Quelleck, and Jeremy Howard, who played the young and very helpful "Galaxy Quest" fan named Kyle.

I highly recommend purchasing "Galaxy Quest" on DVD, which has superior picture and sound quality, and includes several deleted scenes, trailers, biographies, the feature "On Location in Space" and production notes. "Galaxy Quest" is a film that can be watched many times while never becoming tiresome. Sit back and remember those immortal words, "Never give up! Never surrender!" as you are whisked away into the fantastic world of "Galaxy Quest"!

It's been a long time since I've seen a parody film hit its intended targets with such accuracy and finesse. The movie deals with the crew of the Protector, a spaceship that exists only in reruns of the strangely familiar early 80's ensemble SF TV show Galaxy Quest. Exiled to mall shows and science-fiction fan conventions, they live out their days signing autographs for fanatical, show-quoting groupies until they're propositioned by some rather distinctive "fans" for a very special mission...

What ensues is an incredibly fun skewering of the whole Star Trek experience, effortlessly bouncing from knowing parody to rollicking action to heartfelt emotion. And it's all headed by a top-flight cast led by Tim Allen as Jason Nesmith/Commander Peter Quincy Taggart. Aiding and abeting him is his flouncy blonde side-kick, played by...Sigourney Weaver! This brilliant casting coup alone should tip you off to the film-makers' attitude towards the subject matter. Also present is Alan Rickman in an incredible turn as the token alien cast member who longs to return to Shakespeare, Tony Shalhoub as the boggled engineer, and Daryl Mitchell as the cute kid who is now all grown up. But as good as the human cast is, they fade into the background whenever they interact with the true aliens of the picture, the Thermanians. Masking their true squidlike form in a human disquise, they lurch across the screen speaking in stretched and strangled accents with ever-present goofy grins on their faces.

It matters not if you're a bred-in-the-bone Trekkie or wouldn't know a Mark I phaser if it jumped up and stunned you...there is just so much to enjoy here. It probably does help if you're at least familiar with the source of the various in-jokes contained within, but Galaxy Quest is careful to surround its Trekian pokes with a surprisingly touching story of personal redemption.

Sure there are plot holes the size of black holes, and the motivations for the aliens' actions are as vaporous as a plasma cloud. But this is one of those movies that revels in its own wonderous creations so much that you really just don't give a damn about blasted logic. Hurry to the video store today, a video gem like this comes around about as often as Halley's Comet.
