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.

Plot hole: When Kalgan is torturing Lea, he says that he wants her father's countermeasures in case of emergency. But when she is rescued and finds out MacPhearson is a traitor who is working for Kalgan, Captain Devers is worried because MacPhearson knows all of the ship's countermeasures. If MacPhearson knows the countermeasures, then Kalgon does too, so there is no reason to bring it up while he is torturing Lea.
