It looks like Starz is going to be showing the theatrical version of Grindhouse this week. They've been showing the DVD versions of both films for the past month or so, but I think this is the first chance to see the full original program at home outside of a bootleg. Plus, it'll be in HD!
Next showing I see is 12:45am Monday (Sunday night), or earlier if you get an east feed in the west.
I'm excited to see it again, even though I've got the DVDs. Definitely a case of the sum being greater than it's parts.
