I warn you, it seems to be a tad spoilerish, but then again who knows. Either way, i've been waiting years for this so I figured I might as well watch before they take it down and I have to wait another 3 years for another 10 minute glimpse.
Check it out here.. before it's too late!
And in additional Trick 'r Treat news, apparently they're going to be releasing a graphic novel by the same name around the time of the release (tentatively October 2009.) The first few pages they scanned up to the site look pretty sweet. I will certainly be purchasing that little as well.
