"Dexter", Showtime's hit series starring Michael C. Hall as a serial killer who only targets people responsible for murder, has been renewed for a sixth season.
Filming will begin in Los Angeles in the spring of 2011, the cable network said in a statement. Ratings for the current fifth season have increased more than 40 percent since it began in September and are on track to become the show's highest, it said.
In recent episodes, Dexter, who moonlights as a blood spatter analyst at the Miami Police Department, teams up with a female victim of a gang rape and killing operation to target her attackers. Julia Stiles of the 1999 comedy movie "10 Things I Hate About You" and "Eli Stone" actor Jonny Lee Miller guest star.
John Lithgow won an Emmy Award earlier this year for his portrayal during the fourth season of a serial killer who does not subscribe to Dexter's "code". The show also won the award for "Outstanding Directing for a Drama Series". It also won two Emmys in 2007.
Hall battled Hodgkin's lymphoma, a cancer of the blood, over the past year. His wife Jennifer Carpenter, who plays his potty-mouthed police officer sister Debra on "Dexter", said in April that Hall had recovered. The actor was nominated for an Emmy and won a Golden Globe for his role earlier this year.
