The movie's site has lots of stuff, but my favorite perk is the complete soundtrack -- not just samples -- the entire thing. I've never heard of a free soundtrack being made available before the movie came out, or for that matter, after the movie comes out. Jackson sings a couple tracks and does a pretty nice job. The tunes are all gritty down-south blues/rock that's reminiscent of Led Zeppelin -- especially track 4: When the Lights Go Out by The Black Keys. The site also has clips, stills, and blinking pictures of either Jackson's tummy or Ricci's tummy, I'm not sure which it is.
This movie has story. Nice job.
