Stanley Tucci played Dr. Abraham Erskine in the Marvel movie Captain America: The First Avenger and, while he says he will not be appearing in the sequel, he has revealed that Hayley Atwell will be returning as Peggy Carter. Stanley was talking about the Captain America love story when he made the revelation.
Tucci was talking to Collider when he explained, "Oh, it does. And Hayley Atwell, who I just had dinner with last night, we’ve become good friends. I really love that. I really love the relationship between the two of them."
Stanley then admitted that he would not be returning for the movie, revealing that Hayley will be in some flashbacks, "No, they haven’t, unfortunately. I’m really sad. I know that Hayley is going back to do a flashback scene, but I have not been asked."
It will be interesting to see if Hayley Atwell does actually appear in Captain America: The Winter Soldier, since she has said that she won't, while Stanley Tucci says that she will. We still have quite a while to wait, as Captain America: The Winter Soldier is not released until April 4, 2014.
