This is amazing!! I had no idea they filmed this much more! It's funny I was just watching the trailer this morning (I work overnights, I had to keep myself occupied!) and I was thinking I wonder if they had just filmed random moments solely for the trailer, and this is the answer!
I loved this movie (and this series) I just hope they release an extended cut at some point on Blu-ray. If this has an HDTV rip somewhere of course that would be excellent for now, but I'd love an official release, especially considering how many extra scenes there are.
