Continuity mistake: 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.
Continuity mistake: In the scene where Ryder and Lea speak with the mortuary keeper in the deep freeze room, you can see the frozen enforcer to the keeper's immediate right (in his close-up scenes) breathing.
Continuity mistake: In the scene where Kalgan has one of the enforcers beaten up after fooling around with the Ballerians, two different actors can be seen playing the beaten-up enforcer. When Kalgan's sidekick thug pulls the guy off the table, he's a flabby guy with a bowlish haircut and a clean-shaven face. After Kalgan says "soften him up" and it cuts back to the beating, the guy is suddenly thinner, has longish feathered hair, and you can see a mustache when he moves his face to the right after the first punch.
Continuity mistake: In the scene where third engineer Steve Godell is confronted by Kalgan and jumps to his death (with Kalgan's help) from the catwalk, his glasses come flying off when he hits the floor. When the film cuts away and then cuts back to the paperwork falling on his face, his glasses are back on again.
Continuity mistake: When Ryder and Lea are leaving the disco to follow Kalgon, a laser gun appears in Ryder's hands out of nowhere.
Continuity mistake: When Ryder is beamed onto the southern sun, no fire extinguisher is behind him. Yet in the next shot, one appears just where he stood. The next shot there are about five at this place.
Continuity mistake: When Lea tricks the guard into removing his jumpsuit, she presses a high-heeled boot against his stomach. When she escapes and is shown running up a ladder a few seconds later, the high-heeled boots have changed into flat boots that could not have come from the guard.
