Do we assume this is a wide release in October? If so, then I have to wonder if he is going to go to a festival with a jury. He may just do TIFF, he's done TIFF before. Also, they don't seem like they are even doing an awards run with this movie, as normally those are platform releases, which he did with the Wrestler and Swan.
If this is kind of a horror movie, which is what we're hearing, then they may just play it like a horror movie and wide release it. It could do very well at the box office, if it's any good at all.
