Первый мститель
A Marvel One-Shot featuring Peggy Carter was in the works for some time before Atwell signed on to star in it, reprising her role from the "Captain America" films. D'Esposito, co-president of Marvel Studios and an executive producer on the feature films, aimed to replicate the period setting of "Captain America: The First Avenger", while also giving the short a more modern, superhero feel. The film was a more ambitious production than previous One-Shots, with more action scenes and visual effects required than previously. Several other characters from Marvel Cinematic Universe films also appear, including Cooper reprising his role of Howard Stark.
