Actually, if you read the comments on the art page linked to this article, there is valid testimony and evidence that this bug drawing was created long before the movie and has nothing to do with the movie. There's even testimony from the artist himself. All this hubbub proves is that this movie's advertising campaign worked.
It's the same tactic that was used when the the first "Matrix" movie was on its way out and masses couldn't wait to spend money to see that piece of shit either.
