Billy Brown, who starred in the short-lived FX series Lights Out, is the latest actor to sign on for Dexter's upcoming sixth season.

The actor will portray Mike Cutler, a Chicago homicide detective who transfers to Miami Metro and immediately has an impact on the precinct. It isn't known how many Dexter episodes Billy Brown has signed on for. Billy Brown joins an impressive list of guest stars and recurring actors this season including Colin Hanks, Mos (a.k.a. Mos Def), and Edward James Olmos.

Production starts today on the sixth season of Dexter, which will debut sometime this fall on Showtime.
