A couple weeks ago, Marvel showed off their pilot for the highly-anticipated new series, Agents of S.H.I.E.L.D.  Today, they've released plenty of new images, and some that could be considered slight spoilers for fans who would enjoy a pleasant surprise when they see the pilot.  But for the most part, these are images of lead actors Clark Gregg, Ming-Na Wen, Brett Dalton, Chloe Bennet, Iain De Caestecker, and Elizabeth Henstridge.

Hit the jump to check out the images (I've put the ones that could be considered spoilers near the end).  Agents of S.H.I.E.L.D. premieres Tuesday, September 24th at 8:00pm EST on ABC.
