I have to disagree with most of the other reviewers (especially those that can't spell) and unreservedly recommend Space Mutiny for everyone that loves Sci-Fi, or unintentional comedy.
The movie is supposed to take place in the bowels of a "Mother Ship" (footage stolen from "Battlestar..") filled with the third generation of refugees from a dead planet. One of the refugees, ELIJAH (snicker) KALGAN (John Philip Law) by name, decides he's sick of living on the spaceship and wants to live on a "real planet." He hatches a plot to take over the ship, sell the other occupants of the ship into slavery to "Space Pirates" and then live in luxury on a "real planet." Hence the name, "Space Mutiny." Doesn't sound too bad so far, right? Well, that's when Space Pilot DAVE RYDER (Reb Brown) enters the picture, silver lame' pants and all, and the movie starts to turn on the stink.
Space Mutiny is a rock 'em, sock 'em, sci-fi shoot 'em up filmed in an abandoned warehouse that is supposed to be the environs of the previously mentioned spaceship. Did I mention you can clearly see the windows at the top of the warehouse? Other highlights include: characters that die only to reappear later in the movie with no explanation, characters chasing each other in pimped-out floor waxers called "eliminators," Kalgan looks evil with increasingly less enthusiasm, our hero Dave Ryder routinely emits high-pitched "battle screams," unintentional nudity (don't ask), and a guest appearance by the Band's Robbie Robertson as the evil and crippled turncoat officer.
You don't have to be a "Best Brains" member to be able to make fun of this movie, and that's why it stands on its own. It's so bad it's good...DARN good! I'm looking forward to the DVD that has all the deleted scenes; the box cover has clips from several scenes that aren't included in the movie! "Space Mutiny" is well worth the $5 it may cost you, just so you too can thrill to the exploits of the greatest Sci-Fi villain since Darth Vader: KALGAN!
