You know, the clown could just be a decoy, and even if it's not I may be way off the mark, but I was thinking...
Michael Aiello had said on twitter that they managed to secure an IP that he had always wanted to do and was extremely excited for. Now, that could be any number of things, but in the past he's said that every year he pushes for a Killer Klowns From Outer Space house. Again, I may be way off, but it's a possibility... and it's worth pointing out that quite a few of the clowns in that movie had outfits with stars on them.
