Once upon a time, back in 2012, Jessica Chastain was in talks with Marvel to star in 'Iron Man 3' as scientist Maya Hansen. Chastain eventually passed on the role saying, "My schedule is jammed packed and I can’t fit anything else in." (The part would eventually go to actress Rebecca Hall.) At the time, Chastain posted to her Facebook fans, "Hopefully there’ll be another Marvel film in my future." Has that time come already?
