Christopher Heyerdahl must be having a bloody good time playing vamps. The actor played the Volturi Marcus in the Twilight Saga films. Deadline reports Heyerdahl is joining the cast of True Blood as Dieter Braun, a vampire who gathers intelligence of the Authority and enjoys interrogation to secure information. The actor’s resume includes more horror geek cred including Supernatural and Sanctuary.

Christopher Meloni (Law & Order:SVU, Oz) is also joining True Blood next season.
