Jennifer Carpenter is the focus of a new promotional video for the game changing season 7 of hit Showtime series 'Dexter'. The new sequence merges footage of past seasons, teases from the upcoming one all stitched together with an array of floating blood slides and flashy fonts. Michael C Hall returns as everyone's favourite anti-hero at a time when relationships will become more than just frayed particularly with that of Deborah (Carpenter) his police chief sister! Ray Stevenson ('Thor', 'G.I. Joe: Retaliation'), Jason Gedrick, Matt Gerald, Yvonne Strahovski ('Chuck'), Katia Winter ('Arena') and Calista Flockhart ('Ally McBeal') all join the new series along with a host of the usual suspects including C.S. Lee, James Remar, Lauren Vélez, David Zayas and Desmond Harrington ('Wrong Turn').
