HBO has released a poster for Alan Ball’s upcoming HBO series True Blood. In addition to creating Six Feet Under, Ball won an Adademy Award for America Beauty, and directed the upcoming film adaptation of Towelhead. True Blood is based on Charlaine Harris’ “Southern Vampire” novel series. The series follows the world of vampires set in small-town Louisiana. Apparently the vampires are able to co-exist with humans by drinking a Japanese-manufactured synthetic blood. /Film’s David Chen will be reporting from the True Blood panel later this week at Comic Con 2008. The series is set to premiere on HBO starting September 7th 2008.
