Corrected entry: Right after rescuing the princess, they show a radar screen and Lone Starr says that Spaceball 1 is headed toward them. According to the radar screen, it was almost on top of him. Even a leader says in a few shots later that he was a minute away.
Corrected entry: Barf opens a fortune cookie and Yogurt comes out to talk. When he is done talking, he starts to go away. But before he goes away Lone Starr starts talking to Barf as though Yogurt isn't there.
Correction: Lonestar could have just known he was done talking; he'd given them all the information they needed.
Corrected entry: In the scene where Snotty is ordered to beam down Skroob, Snotty did something wrong and that causes Skroob's head to be put on backwards. When everyone is trying to fix the problem he looks down and grabs his butt - this means his hands must be backwards too. Also if you look closely you can see his feet aren't backwards either. (00:15:25)
Correction: No one said specifically that only his head was on backwards. Since the beaming went wrong, his hands and feet could have turned out backward, yet everything else stayed the same.
Corrected entry: When Barf and Lone Starr (in disguise) find Princess Vespa and Dot Matrix in the prison cell, they take off their helmets. When they leave the cell, they don't have their helmets. When they run into the 2 guards they beat up, the GUARDS are wearing the helmets.
Correction: The heroes have obviously left their helmets in the cell but the two guards they beat up to get the helmets got new ones (most likely to be ID'ed as guards) and notice they had also gotten themselves new guns as well since the heroes still had the guns stolen from the guards earlier so these are not the same as all guns and helmets look dead identical.
Corrected entry: When Barf and Lone Starr take the clothes of the two guards, they take their guns, but when they all meet up in the corridor, the guards have their guns back.
Correction: These are new guns as there is no doubt an armory where they retrieved new weapons. Lone Starr and Barf still have the stolen guards' guns.
Corrected entry: When Princess Vespa goes on a rant and ends with 'Daughter of Roland, King of the Druids.' Lone Starr says 'Great, a Druish princess.' He should already have known she was Druish, considering he apparently knew who King Roland was when he called.
Correction: He did it for the joke.
Corrected entry: In the scene near the end of the movie where Lone Starr puts shaving cream on the guard's face, after he does the death pinch he falls and Lone Starr's ring falls off. But in the next shot it is on again.
Correction: If you go frame by frame you will see that his ring stays on and the thing that falls is probably some shaving cream.
Corrected entry: When Lone Starr and Barf leave the ship after it lands to rescue the princess in Spaceball city, the door to the ship is left open. Upon their return to the ship with the princess, the door is closed and then blasted locked. (00:59:15)
Correction: The guards they knocked out are left in the ship. Later on they run into these guards inside the prison complex. The guards left the ship, closed it and locked it. So they wanted to prevent a fast get away of Lone Starr & Co.
Corrected entry: When Barf opens the roof of Vespa's car, the stars behind them are not moving considering the car is being tractor beamed in.
Corrected entry: When Lone Star and Barf are carrying Princess Vespa and Dot Matrix respectively in the desert, just after Lone Star and Vespa collapse in the sand, they fall with their faces looking at opposite sides. And seconds after, when the small guys come to help, Vespa's head is looking at the same direction than Lone Star. This couldn't be possible if she was unconscious.
Correction: We do not know how much time passes before the little "dinks" arrives at the scene. After Lone Star falls, the movie cuts and we are shown the little guys walking through the desert. It is entirely possible that more time than the second shown on screen passed, and if Vespa regained some consciousness or semi-consciousness in this time, she could have turned her head.
Corrected entry: When Princess Vespa comes out of Yogurt's tunnel, she says, "Daddy, is it really you?" but her lips don't move.
Correction: Colonel Sanders said "In less than a minute, Lone Star will be ours". Obviously he included the time needed to pull the Eagle 5 with the laser beam and then place it on the ship's dock.
