The Avengers director, Joss Whedon, wrote a version of the movie with the Wasp in Black Widow's place. The reason for that is Scarlett Johansson was having scheduling conflicts, so it seemed for a time that she would not be able to appear. Whedon wanted New Girl star Zooey Deschanel to play the Wasp. I have to say that I would have loved to see Deschanel as Hope van Dyne. While I like Evangeline Lilly's version of the character, Deschanel's comedic talents would probably have made for a more exciting Wasp. However, I'm happy Black Widow was in The Avengers.
