Gianna Sobol posted on the Inside True Blood Blog that they were doing a casting call this week. The roles they were casting this week was for wolves. The wolves were distracted, by the help of the trainers with chicken treats, so that Alan Ball and several others (producers, directors, ADs, cinematographer) could look on and discussed which wolves to cast for what character. The photo was taken by Alan himself at the first meeting with the wolves.
