On Tuesday, it was announced that Colin Hanks would take a trip to Miami and enter the always dangerous orbit of blood splatter expert/serial killer/good guy Dexter Morgan. Now, his role on the Showtime hit has been revealed.According to TV Line, Hanks will play "highly intelligent young expert on ancient artifacts who gets linked to a series of grisly murders in Miami." That, of course, would place the Miami Metro Police Homicide Department hot on his trail -- and put him square in the sights of Dexter.Then again, he may not be the bad guy -- the show's producer has previously stated that there will not be one main guest star villain for Dexter to chase, as there has been in seasons with John Lithgow and Jimmy Smits.
