We are a month away from the premiere of Agents of S.H.I.E.L.D. and the return of Clark Gregg in the role of Agent Phil Coulson who assembles a small, highly select group of Agents from the worldwide law-enforcement organization known as S.H.I.E.L.D. Together they investigate the new, the strange, and the unknown across the globe, protecting the ordinary from the extraordinary. Yesterday a new promo clip surfaced, which even has some new footage. Check it out below. Agents of S.H.I.E.L.D. starring Clark Gregg, Ming-Na Wen, Brett Dalton, Chloe Bennet, Iain De Caestecker, and Elizabeth Henstridge, premieres Tuesday, September 24 at 8pm EST this fall on ABC.
