Some Agent Carter info from SDCC.
I particularly like that last sentence.
"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.
