We just recently learned that Colin Hanks would have a major character arc appearing in all 12 episodes on the forthcoming sixth season of Showtime’s serial killer drama series Dexter, and now another name has surfaced for a major role. THR reports rapper turned actor Mos Def (Be Kind Rewind) will also have a multi-episode arc on the hit series. Production will begin in June with Mos Def playing a hardened ex-con who claims to have found religion yet seems to continually find himself surrounded by violence. Apparently Dexter will actually reveal the truth behind who this man really is behind the front. Meanwhile, the report also reveals Hanks’ character will be a man name Travis, the main nemesis of the sixth season and a highly intelligent ancient artifacts expert who is linked to a series of grisly murders in Miami. Sound good?
