Back in August, we reported a rumor that Marvel's Ant-Man may include certain characters from Captain America: The First Avenger, including Hayley Atwell's Peggy Carter, Dominic Cooper's Howard Stark, Toby Jones' Armin Zola, and a younger version of Alexander Pierce, a character played by Robert Redford in this year's Captain America: The Winter Soldier. While the other characters have not been confirmed yet, a new casting notice reveals that Hayley Atwell has joined the Ant-Man cast.

Take a look at the casting call below, which is seeking actresses to play Hayley Atwell's stand-in.

"Casting directors are looking for an actor to work as a stand-in for the actor Hayley Atwell'. Hayley Atwell is 31, 5'7 and 112 pounds. She is best known for her work in stage productions such as A View from the Bridge, and in films such as Cassandra's Dream, The Duchess, The Pillars of the Earth, and Captain America: The First Avenger. In addition, casting directors are looking for a body double that meets certain requirements."

The original rumor revealed that Hank Pym takes a meeting with S.H.I.E.L.D. founding members Peggy Carter, Howard Stark, Armin Zola and Alexander Pierce, although no details about that meeting were given. We reported back in January that Ant-Man begins in the early 1960s, with Hank Pym fighting Communism, before shifting to the modern-day Hank Pym, played by Michael Douglas. It was reportedly this scene featuring other members of the Marvel Cinematic Universe that lead to the departure of director Edgar Wright back in May.

Hayley Atwell is also reprising her Peggy Carter role for the ABC TV series Marvel's Agent Carter, which debuts in mid-season. What do you think about Hayley Atwell returning for Ant-Man? Chime in with your thoughts below.
