TV's favorite serial killer will return for seasons 7 and 8. Showtime had been negotiating with Michael C. Hall for future seasons and talks must have gone well, because they just announced that Dexter has been renewed for two 12-episode seasons. At this time it isn't known whether the plan is to wrap up the show by the end of season 8 or if there is the possibility for future seasons beyond that.
Showtime president David Nevins had the following to say: “Dexter‘s enormous success is a real tribute to the great achievements of its cast, producers and the powerhouse performance of Michael C. Hall... The series is bigger than it’s ever been in its sixth season… Together with Michael, the creative team on the show has a very clear sense of where they intend to take the show over the next two seasons and, as a huge fan, I’m excited to watch the story of Dexter Morgan play out.”
