That's the really nice part about the exhibitor screening (which this is). It's only a select few and they don't "sell" tickets to it. You are registered and you just show up. There is no need to wait in line because nobody needs to buy tickets and there is nothing "first come first serve" about it. The openings you need to avoid are the ones a few days before the movie actually opens to the public. That's where the cooks hang out!!
... and you guys are right of course. It is just a movie, however, I'm more excited about being one of the first 200 people in North America to see it.
