This movie is going to be a hoot! And it's a hard R rated movie with tons of blood, violence and gore in it. Hopefully Lions Gate doesn't cut it to shreds for a PG-13 theatrical release.
From what I gather, it'd be basically impossible to do that and keep it even coherent. But fortunately, the film is rather modestly budgeted and the buzz is very high on it, so I wouldn't be too worried about this.
Looks like it'll be great. On another note, what the hell is up with the delays on the comic issues? It's sooooooooo slow.
