The latest "declassified" Level 7 promo video for Joss Whedon’s Agents of S.H.I.E.L.D. focuses on Clark Gregg as Agent Phil Coulson, the most well-known member of the cast of the ABC TV series that is slated to debut on September 24th.  This one-minute clip does deal with the fact that Coulson apparently died in The Avengers, and, though the exact method of his resurrection is not specified, there is a look of shock on the face of an agent with Level 6 clearance who meets a very much alive Coulson, who welcomes him to Level 7.
 
Clark Gregg then goes on to describe Agents of S.H.I.E.L.D. as a "something we’ve never seen on TV before, it’s got action, it’s got great characters, and it’s got humor."  Also with no fewer than two science officers, the show may also bring a little more "hard science" to the superhero genre (see "Will Science Matter on the New 'S.H.I.E.L.D.' TV Show?").
