As bartender/shapeshifter Sam Merlotte, Sam Trammell has been a part of True Blood from the start. With the season-six premiere ahead this weekend, we sat down with the actor, who filled us in on exactly where the action will pick back up. As previews for the show have suggested, it sounds like the war between humans and vampires will escalate this year, and Sam said we'll learn more about "what they can do and who they are" when it comes to the latter. Sam also talked about staying in shape while shooting a show that frequently requires its cast members to strip down and what it was like having his costar Stephen Moyer as a director. True Blood returns this Sunday night to HBO.
