 CONT: When Zorg is getting the case of stones from Achnaut and his  crew, Zorg lifts the lid from the case. You can see the position and  number of the alien crew behind him as he does this. While the lid  is still open, it cuts to a different take of the lid. When Zorg  shuts the case, you can see that the number and position of the  aliens behind him have changed radically.
