I had completely forgotten about this film. I had read some early reviews about 6 months ago but haven't heard much of anything since. Just checked out the site and they have a R rated trailer up. This flick looks absolutely 100% freakin awesome. I love both Clive Owen and Paul Giamatti.
Go to the offical site: http://shootemupmovie.com/
Once the page loads, there will be a bit of red text that says "View Age Restricted Content". Fill out the little bit of age verifiaction (birthday) and watch the trailer.
I can't wait for this film to come out!
