Did you know there's an asteroid that's going to be zipping past earth on Halloween? How cool is that? And imagine the stories you can find in that asteroid. An alien invasion that comes face to face with themselves (in costumes, of course). Gamma rays that turn everyone into the persona of the costume they're wearing. Perhaps the asteroid hits the earth creating a new monster. You have the makings of both humor and horror with one simple asteroid framed with a Halloween theme. Let your imagination soar.
And here's another link to the story with a little more info.
