Revealing mistake: When the van drives upstairs, you can see that it wasn't destroyed.
Revealing mistake: Whilst Bobby is reversing the truck before hitting the flagpole in Bill's yard we see the driveway in front of the truck. The very next shot shows Peggy from behind the truck instructing him how far to go to the flag pole and you can see they have used the same background as the shot before from the other angle. You can tell this as both shots are the same background as both angles despite from different viewpoints are exactly the same items and objects in both shots. Added to this there is a driveway in each shot, and Bill doesn't have 2 driveways in his backyard.

The glass in one spot is flickering around like TV static. (00:07:10)
Revealing mistake: When the narrator says that Superman can leap a tall building in a single bound and shows Superman doing so, you can see in the background by some trees, an odd animation glitch. A curved, thin black line by the trees wiggling back and forth. (00:01:55)

Beyond Good and Evil: Part 1 - S4-E8
