Dexter lands a commanding presence

Commander Adama is moving to Miami. Showtime has announced that actor Edward James Olmos will be joining the cast of Dexter for its sixth season, premiering this fall. Little is known about the plot, though Olmos will be portraying an enlightened religious studies professor. Also cast for season six are Mos Def and Colin Hanks.

Showtime President David Nevins has said that season 6 would bring Dexter back to his roots and be more like earlier seasons. We'll find out what that means this fall.
