Continuity: When the people that live with Yogurt go to help Captain Lone Starr and everyone else with him in the desert, three people go to help Barf and Dot, but when it shows each group two are helping Barf and two are helping Dot.

Continuity: When Princess Vespa's Mercedes is being pulled into Spaceball one, the speed and position of the Mercedes changes.

Continuity: When Lone Starr 'knocks out' the guard who was shaving, the guard's grey key card falls to his side, but in the next shot the key card is laying on his butt.

Audio problem: When Princess Vespa comes out of Yogurt's tunnel, she says, "Daddy, is it really you?" but her lips don't move.

Revealing: Before Yogurt's statue falls on Barf's leg and makes it flat, you can see that his leg is already flat.

Continuity: In the beginning of the movie, when Princess Vespa runs away from her wedding, she gets into a white vehicle. The next shot of the vehicle it is pink, then the next shot it is white again.

Continuity: When Barf and Lone Star are rescuing Dot and the princess for the first time (from the Mercedes), they position their ship over the Mercedes but facing the other way (ie. facing Spaceball 1). However, in the interior shots showing Lone Star in the cockpit, the view is just clear space. Spaceball 1 is a gigantic ship, and they are very close to it (as well as angled slightly up to it), together with Spaceball 1's "mouth" being open which makes the ship even bigger vertically. It should block their entire view, but it's not seen at all.

Continuity: When Helmet is trying to hit Lone Starr with his Schwartz but Lone Starr is holding his head, you can easily tell that Helmet's Schwartz is made shorter so it won't hit Lone Starr.

Continuity: When Vespa starts to run from the wedding, Valium isn't holding anything but as she goes by he is holding flowers. I don't think Vespa handed him her flowers as she ran by because the flowers he is holding are much smaller than the ones she had.

Visible crew/equipment: When Pizza the Hut is telling our heroes that they owe him money, watch his mouth. You can see the actor's real mouth appear a couple of times through the whole speech. The actor's chin is covered in the special effect pizza stuff, but you can still see his very human mouth every so often through this segment.

Continuity: When Colonel Sanders and Dark Helmet meet to discuss Vespa's disappearance, Dark Helmet looks into the periscope and sees Lone Star's ship right behind them. But when they show the periscope Dark Helmet is using there is no view from the other side. How can he see from the other side of the periscope with no window there?

Deliberate "mistake": When Lone Starr and Barf rescue the princess and the 4 of them are trying to escape through the closing vertical door, if you look closely, you'll see that the door's hole goes from being really small when they're running, to really large when they reach it and jump through.

Continuity: In the scene where Dark Helmet and Col. Sanderz turn off the picture, they turn it back on and we see the nurse making out with the doctor. She hurriedly zips up her dress. However in the next shot her dress is unzipped again.
