During New York Comic Con, Marvel Entertainment's head of television Jeph Loeb shared spoilers for Season 2 of "Agent Carter."

According to the International Business Times, along with stars Hayley Atwell (Peggy Carter) and James D'Arcy (Edwin Jarvis), Dominic Cooper will also be returning to the cast as Howard Stark, Iron Man's father.

The revelation came when Loeb presented a video of Atwell and D'Arcy, who greeted fans and then introduced Cooper.

Cooper's return to the series was up in the air because of his commitment to the new AMC show "Preacher," based off of the comic books of the same name, but it looks like the actor will be able to commit to both shows.

Besides Atwell, D'Arcy and Cooper, Enver Gjokaj, who plays Daniel Sousa, Chad Michael Murray, as Agent Jack Thompson, Lyndsy Fonseca, as Angie Martinelli, and Bridget Regan, who plays assassin Dottie Underwood, will all be returning for Season 2, reported Entertainment Weekly.

Besides returning cast members, four new additions for Season 2 were announced. "Devious Maids" actor Reggie Austin has been cast as Jason Wilkes, and Lotte Verbeek will play Jarvis' wife Ana.

Perhaps the most anticipated casting was that of Season 2 villain Whitney Frost, aka Madame Masque, who will be portrayed by Wynn Everett. Currie Graham will be playing the new villain's husband Calvin Chadwick.

Back in August, executive producer Tara Butters revealed that Agent Carter would be taking on Madame Masque, a Soviet assassin with a Black Widow-like storyline, who will make things very complicated for Carter and the SSR when the series returns early 2016.

Besides plot spoilers, fans at Comic Con got their hands on a poster of the latest promotional image for Season 2, featuring Atwell front and center with Hollywood behind her.
