In the TV room, when Mike Teevee says "lights, camera, action!" The camera operating Oompa loompa puts on his goggles, then a couple of seconds later it shows the same oompa loompa putting on his goggles again with a surprised look on his face. I found this mistake myself and I was the first to publicly publish the mistake. It has been verified by Wolper Pictures and Warner Bros. as a simple editing mistake. I give myself a pat on the back for that one.
