while I'm not going in my full ghost-face costume, i will try to wear my nice EU mask and my black hoodie.
Other than when the dark knight came out opening weekend the ushers dressed as joker and batman, at least here in the states people dont really have the zest for the full fun movie experience anymore.
something like the opening in scream 2 (stab 2) would be a dream....minus the stabbing of course
