Deliberate mistake: When Howard walks up to the front of the church he is alone. Suddenly, when his bride comes out, the best man, maid of honor and flower girl are at the front of the church. This happens despite the fact that the music flows and there was not time for the others to enter.
Deliberate mistake: At the end of the movie Rocketman shows his lady friend a space blanket, out of which he states he made something: ballroom dancing outfits. The difference in the material is just too obvious for this not to be a deliberate mistake. The outfits aren't the slightest bit related to the foil they were supposed to be made of.
Deliberate mistake: In the very first scene, with Dave, Gaz and Nathan in the abandoned steel works, they only have one girder, but when they're on the car in the middle of the canal, they have two: one balancing on the car roof, and the one Nathe walks across.
Suggested correction: There's been a time skip between the two scenes. They found another girder and took that one as well.
Deliberate mistake: In the final scene when the four cars are driving away there is a road sign that shows how many miles it is to Chicago (where the main characters are from). In reality there would not be such a sign because there is not one direct route from Vegas to Chicago. A typical road sign would show the nearest cities.
Deliberate mistake: When Buddy's dog box falls out of the back of the truck the dog box is empty.
Deliberate mistake: In the finale when Kadeem Hardison is beat up by the motorcyclists he performs a back somersault. As he falls to the floor, you see a white guy's back, despite the character being black.
Deliberate mistake: Every time George swings into a tree, there is a George shaped impression created. However, in the next scene the tree is back to its natural shape.
Deliberate mistake: As the Mondo Burger building is falling apart, customers and employees run out the doors. The glass doors then shatter. Not only do they break at the exact same time, there was nothing to make the windows shatter as hard as they did. (01:25:51)
Deliberate mistake: The shot of Orbison's house buring at the end is quite obviously fake. You can see that it's made of cardboard and paper, and even the windows burn and curl like normal bits of paper do when set alight.
Deliberate mistake: As Roper drives the Dodge into the shipyard watch the underside - no sign of McCall, even though he's visible under the body when he comes out of hiding.
Deliberate mistake: Directly after Nicola has her baby, she sits up and holds a baby that is clean, umbilical cord-free, and has teeth. There is no possible way this could happen.
Deliberate mistake: Throughout the whole short film, Geri's hair doesn't move or react to anything (such as the wind or his glasses). The glasses even seem to go through his hair without any movement in his hair. (00:01:00 - 00:03:35)
