Michael C. Hall can't do it all by himself.

Granted, the multiple-time Emmy nominee is in almost every scene of Dexter, but he'll be supported by a number of big names on season six. There's Edward James Olmos as a mysterious professor of religion; Colin Hanks as his protege; Mike Anderson as a new detective; Aimee Garcia as Batista's sister; and Mos Def as a possible rehabilitated ex-con.

Get to know each of these characters a bit better in the following promo, and bookmark our Dexter spoilers section for season-long scoop...
