Its really funny that you mention that because I was actually casted as an extra in the film. It was filmed in June at Mount Rushmore... it was FREEZING that night, we shot until 5am, and I threw up 5 times because I was sick!!!.
All for a low-rate movie!!!
But it comes out Christmas Day... look for me, I'm wearing a white sweater and eating popcorn while looking at the fireworks behind the mountain!!!
(Plus I got paid like $100 so...)
