Although Hayley Atwell reportedly said just last month she wouldn't be reprising her role as Peggy Carter in Captain America: The Winter Soldier, it now appears those plans may have changed.

In an interview with Collider, her Captain America: The First Avenger co-star Stanley Tucci discussed how much enjoyed playing Dr. Abraham Erskine, developer of the Super-Soldier Serum, in the 2011 Marvel film. And while expressed disappointment that he hasn't been asked to return for a flashback, he revealed Atwell has.

"I’m really sad," he said. "I know that Hayley is going back to do a flashback scene, but I have not been asked."

Atwell would join fellow original cast members Chris Evans (Captain America/Steve Rogers), Sebastian Stan (Bucky Barnes/Winter Soldier), Toby Jones (Arnim Zola) and Samuel L. Jackson (Nick Fury), along with Cobie Smulders (Maria Hill), Scarlett Johansson (Black Widow), Anthony Mackie (Sam Wilson/Falcon), Emily VanCamp (Sharon Carter) and Frank Grillo (Crossbones).

Directed by brothers Anthony and Joe Russo, The Winter Soldier is believed to be based on the Captain America storyline of the same name, which revealed Captain America’s sidekick Bucky Barnes didn’t die as expected during the war. Instead, an amnesiac Bucky got snatched by the Soviets, fitted with a bionic arm and programmed to serve as an assassin known as the Winter Soldier. The secret is revealed in the present day after Barnes attacks the Red Skull and blows up part of Philadelphia. The film opens in 3D on April 4, 2014.
