Thus far, we've seen a poster for the fourth season of Dexter, as well as a full promo that ran to over three minutes. Neither of these did anything but increase our anticipation of the return of Dexter, as the show's fourth season is now just over a month away.

Dexter returns on 27th September, with the added bonus of Mr John Lithgow in the cast, and Showtime has put together another stylish promotional piece for the new series. It's only 30 seconds long, but it's a really nice piece of work.

Given just how impressive the last season of the show was, we've got high hopes for season four of Dexter. So feel free to whet your appetite by pressing play below...
