For those who weren't up that early, we have the full video for you right here, which features a tour of "The Bus" set, a massive aircraft that doubles as this S.H.I.E.L.D. team's base of operations. We also hear from cast members Clark Gregg (Agent Coulson), Ming-Na Wen (Agent Melinda May), Brett Dalton (Agent Grant Ward), Chloe Bennet (Skye), Iain De Caestecker (Agent Fitz) and Elizabeth Henstridge (Agent Simmons).
