Following a slew of “mini trailers” and one brief teaser, the first full trailer for the upcoming fifth season of HBO’s True Blood has gone online.  The clip shows quite a bit of footage from the upcoming season, including the promise of a prolonged Bill/Eric team-up (please tell me a buddy vampire spin-off is in the works), the return of an old fan favorite character, and the promise of more of that weird clown face that apparently appears when witches get high or something.  However, the best part about this trailer is Mr. Christopher Meloni.  He joins the cast this season as the head of The Authority, a council made up of the most powerful vampires in existence.  If you remember the predicament that Bill and Eric found themselves in last season and compound that with the returning baddie, you should have some idea of where this promisingly badass Meloni character comes in.Hit the jump to watch the trailer, and if you missed all the character posters that were recently unveiled, click here.  The fifth season of True Blood premieres on HBO on June 10th.true-blood-poster-christopher-meloni
