Continuity: While this movie is so bad and full of mistakes, its barely worth finding them all, one stands out in the history of movie mistakes. One of the officers on board the ship, Lt. Lamont, is killed by the villain. A few scenes later she shows up on the bridge as an extra.

Space Mutiny mistakes
Revealing: Apparently filmed inside an old warehouse, heavy masonry walls can be observed during some scenes inside what is supposed to be a spaceship.
Audio problem: In the scene where Kalgon is torturing Lea Jansen with a dental drill, you see it is some sort of laser, but you can hear a drilling sound.
