The first footage of ABC's highly anticipated Joss Whedon comics adaptation, Marvel's Agents of S.H.I.E.L.D., has hit the web.

The short teaser might be just seven seconds, but it's packed with action as The Avengers' Clark Gregg reprises his role as Agent Phil Coulson. The footage, posted Sunday, bills the new series with a built-in Twitter hashtag of #CoulsonLives and the following tagline: "The saga that began with Marvel's The Avengers continues on television."
