By the end of the first season of Marvel's Agents of S.H.I.E.L.D., the titular spy agency was officially dismantled, with Phil Coulson left in charge of rebuilding the organization from the ground up. As a result, when the ABC drama returns, fans can expect the series to go "back to basics," according to star Clark Gregg.

"You've got to rebuild S.H.I.E.L.D. from the ground up in a much more dangerous world where your group is outlawed,"  he told Collider. "So it feels like the early, Sean Connery James Bond with the brass knuckles and not afraid to knock somebody off."

When S.H.I.E.L.D. returns, it'll be in a new time slot (Tuesdays at 9 p.m. ET/PT), which allows for "darker" storytelling, Gregg said, "like I think Marvel needs to be." Additionally, Gregg said the fact that S.H.I.E.L.D. will run with few interruptions, save for a hiatus filled by Agent Carter, is a huge leg up over Season 1.

"Nobody could get a momentum going and when the show started to be on consistently and having story that carried over in an episodic way, that's when things started to click," he said. "For the most part, [season two features] straight runs of our show, which is when I think it really works."
