Corrected entry: When the ship is going to self-destruct, the P.A. says it will blow up in 3 minutes, but it takes longer than that.
Corrected entry: When Lone Starr and Barf rescue Vespa and Dot early in the film, Barf descends down a ladder to the roof of the Mercedes. The door opens up, he introduces himself, etc. and then he, Vespa, and Dot climb up the ladder with Vespa's luggage. This entire scene is completely impossible because both Vespa (human) and Barf (half dog, half human) would not be able to survive in outer space without an astronaut-type suit. The average temperature in outer space is approximately -455 degrees Fahrenheit. Also, space is a near vaccuum, so there would be no air to breathe. Thus, Barf would've never been able to make it out of the Winnebago to rescue Vespa and Dot alive.
Corrected entry: When the cast member is struck by the lightsaber he falls to the ground and is left there. Later when they are fighting he is gone.
Corrected entry: When President Scroob is beamed to the next room, his head is on backwards. When he pulls away the back of his coat and says, "Why didn't somebody tell me my ass was so big?", his hands are angled like they are backwards as well. His palms are pointing towards his back. They should be facing the other way, as well as his thumbs being reversed.
Corrected entry: When Lonestar and Helmet are fighting near the end, Helmet takes Lonestar's ring. In one scene after this he is standing near the self destruct button. The camera operator is visible in the glass of the button. It is clear enough you can see that he is wearing a "Spaceballs" shirt.
Corrected entry: After Spaceball1 takes the air from Druidia, King Roland falls on his desk. Later, when the air is back, he is on a different part of the desk.
Corrected entry: Watch Dot's legs at the wedding, when she says, "I was so excited, I couldn't hold my oil!" If you look underneath her, you will see some lines, the track for her to slide on or a mark where she's supposed to be.
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.
Corrected entry: In the beginning story narrative, there are four paragraphs, double space. But when they are fast-forwarding through it later, there is only one paragraph. There is also a Sub-Title underneath the "Chapter Eleven." There is also no double spacing, and the "If you can read this you don't need glasses," shows up before the rest is almost all the way up.
