In anticipation of the HBO premiere of season three of "True Blood" on June 13, the network will host special screenings in 50 theaters across the country on June 1 at midnight.

"True Blood" fans can enter to win VIP passes to the screenings via a "True Blood" Facebook Sweepstakes. Upon registering, fans will be asked to come out as either a vampire, shapeshifter, werewolf or a fangbanger.

Zach Enterlin, HBO VP of advertising and promotions said in a statement, "’True Blood’ has some of the most passionate fans of any show on television and we are excited to have an opportunity to reward those viewers on a national level."
