Friday during a red carpet interview leading into Comic-Con International: San Diego, IGN conducted several interviews with those involved in both Agents of S.H.I.E.L.D. and 2015's Agent Carter television series and came away with some surprising information. Chief amongst those was the fact that the ever-present butler from Avengers comics, Edwin Jarvis, would debut in Agent Carter as the butler for Howard Stark.
"I can tell you you'll get Edwin Jarvis ,who is Howard Stark's butler and is an important force in Tony Stark's life," said Stephen McFeely. "He'll be an important ally for Peggy, and as being an emissary for Howard Stark, he might have access to tech."
McFeely and fellow Executive Producer and writer Christopher Markus said that Agent Carter is being approached as an "8 hour movie" with "one story, one bad guy, with lots of twists and turns." The duo said that while Hydra is on the table for use in the series, the fact that Arnim Zola revealed what Hydra did after World War 2 in Captain America: The Winter Soldier it changes how they would approach it in the post-WW2 era of Agent Carter. They did say that Agent Carter would feature a major Marvel villain, but balked at naming who.
In another interview, series showrunners Tara Butters and Michele Fazekas said that while in the long-term Agent Carter will showcase how the SSR transforms into S.H.I.E.L.D., the debut of S.H.I.E.L.D. won't happen in the first season. Also, the pair were asked about a tidbit of information given out in the Agent Carter teaser from Friday night regarding Howard Stark being branded a traitor, but they both said "no comment."
