This science fiction comedy has an interesting premise. The cast of a classic sci-fi television show, Galaxy Quest, has been spending the last several years doing little else but appearances at Galaxy Quest conventions -- until real aliens find them. The joke, of course, is that Galaxy Quest is Star Trek thinly disguised. Even the titles of the two shows aren't so very far removed from each other.

As silly as the movie sounds, I found it quite funny. Science fiction fans, in particular Star Trek fans, will probably like it. This is one of those escapist flicks that just works; in spite of the unreal premise and emphasis on humor, we slip into the story quite readily. It's easy to have fun with this one.
