The hole Croker burns in the front door with his ray gun is no longer there when other characters show up.
During the montage where My-ik and Du-ug are building the flying bicycle, the patch on My-ik's jumpsuit shifts from the right side to the left.
When My-ik and Du-ug are chasing the cow, we see a close-up of the cow swishing its ears before charging them and there's a horse in the background running backwards.
The last shot of the movie is a long, pull-away shot from high above the actors. As the camera pulls further back, the branches of a tree that were snagged by the camera equipment and cherry-picker abruptly snap into view as the equipment passes by and releases them.
In the cast credits, Elden Henson's name is spelled incorrectly, as "Eldon Henson".
When trying to behead the cow, you can hear My-ik revving up his chainsaw, yet the chain isn't moving.
While My-ik and Du-ug are serving food in the food truck at the end of the movie, the shadow of the boom mic is visible at the top of the screen.
