The DVD will contain simply a The Collinses: Every Family Has Its Demons featurette. The Blu-ray, meanwhile, will have that featurette, a Maximum Movie Mode option plus deleted scenes. That's the art you see below.
When we spoke to writer Seth Grahame-Smith about the film earlier this summer, he told us, "I encourage people to really look at the deleted scenes when this Blu-ray comes out because there's like a whole movie that was cut because it ran so long."
Hope that still holds true - I'm curious to see how many deleted scenes are on the Blu-ray.
