Edward J. Olmos, one of television's most recognizable faces, has joined the cast of Showtime's Dexter for its sixth season, according to Deadline. He will play a "brilliant, charismatic professor of religious studies.

Although exactly how the character will fit into the plot is currently unknown, one would assume that Olmos' character will somehow play a part in Mos Def's storyline of an ex-con who's had a spiritual awakening. The veteran actor has a long and storied history in Hollywood, having appeared in Ridley Scott's Blade Runner, the 1988 classic Stand And Deliver, and, most notably for geeks, as Admiral William Adama in SyFy's Battlestar Galactica.

Olmos joins the aforementioned Mos Def and Colin Hanks in Dexter's latest season, with production recently underway in Los Angeles. In one of the most celebrated series on television, Michael C. Hall stars as a blood-spatter expert for the Miami police department who moonlights as a serial killer. Dexter will make its return to the boob tube this fall.
