Showtime has released a short teaser trailer for season seven of Dexter featuring tons of never-before-seen footage.  The catch?  It all blurs by in about five seconds.  Try as I might, I wasn’t able to capture any images of the show’s newcomer, Yvonne Strahovski (Chuck), so she may or may not be featured in the teaser.  People who are featured include Michael C. Hall, Jennifer Carpenter, David Zayas, James Remar, C.S. Lee and Desmond Harrington. Obviously, if you haven’t caught up to the dramatic conclusion of the season six finale, you should steer clear of any of the following information as it contains heavy spoilers.  Dexter returns to Showtime for its seventh season starting September 30th.  Hit the jump to check out the teaser.

Dexter is a show that works thanks to a Herculean effort by Michael C. Hall.  The show is founded on a precarious premise that depends on you investing in the adventures of a serial killer, anchored by a sardonic inner monologue and visions of a dead father.  And with Chip Johannessen (24) taking the reins for the new season, Dexter is on its third showrunner in five years, which messes with the auteur theory.  It’s not the effort of a singluar creative vision that holds the show together as Showtime’s flagship drama — at least not behind the camera.

Hall is brilliant.  He has three Emmy nominations (plus a fourth for Six Feet Under) to prove it.  Is it any surprise that he’s no less brilliant in the first three episodes of season five, reacting to the closing events of last season in which… Oh.  Wait.  This gets into spoilers for the first four seasons from here on out.  If you’re cool with that, you can find my review of the first quarter of season five of Dexter after the jump.
