An incredibly packed seven seconds of footage from Marvel's newly greenlit Agents Of S.H.I.E.L.D. has hit the web, ahead of the full trailer reveal later today. You can watch the trailer for yourselves below and trust me, there's plenty of footage to still-frame, dissect and discuss before the full thing airs on ABC with the season finale of Once Upon A Time in the US tonight. One thing in particular that seems to have fanboys' tongues wagging is the potential reveal of Luke Cage. Take a look for yourself... could he be the black superhero who is about to make their debut on the small screen? Coulson Lives! Things have been moving at neck break speed on Marvel's Agents Of S.H.I.E.L.D. On Friday, the show was officially put to a series order from ABC, then we got our first look at the cast photo and logo, and now a full trailer later tonight. Starring Clark Gregg's return as Agent Phil Coulson and his team of elite S.H.I.E.L.D. members, the show itself is expected to air later this year.
