A promo trailer for Zack Snyder's mythical spartan flick 300 has hit the web and it looks AMAZING. The movie of course is based on the Frank Miller graphic novel (haven't read but always wanted too) and will hit cinema's in March next year. Just like Frank Miller's other series Sin City, the movie was shot with a combination of live action and green screen backgrounds to bring the unique look and feel of the graphic novel to life.
