The IESB are housing a fairly badly encoded version of the Trick'r Treat trailer, but I want to send you over right away as this is very much one of my most eagerly anticipated films.
Expect a direct download link when I can source one.
Oh - and note that the trailer announces a release date of October. Seems that Box Office mojo had us all worried over nothing.
[EDIT: Verbal supplied the direct download link for this dodgy encode - I was meaning we'd hold out for something better than a tagged flv. But, actually, it's pretty cool Verbal did this. So say thanks to him]
