Joss Whedon said in an interview that he wrote a scene with Steve and Peggy while writing
Avengers, even though he knew that he would never be able to fit it into the film. The scene would have had Steve visiting a 97-year-old Peggy in a Veteran's hospital and would have allowed Steve to go on a patriotic speil about how we treat our veterans. He said that writing that scene, even though he knew it wouldn't be in the movie, was his favorite scene to write in the whole A
vengers experience.
