Initially the duo were hired by Marvel Studios to write the script for Captain America: The First Avenger, but not only did they go on to pen the entire Captain America trilogy, but they also developed both Avengers: Infinity War and Avengers: Endgame with directors Joe and Anthony Russo (not to mention they also created the Agent Carter television show).
In the last 11 years, few filmmakers have had as big an effect on the Marvel Cinematic Universe as Christopher Markus and Stephen McFeely.
That’s an impressive track record all by itself – but fans will be excited to know that they still feel they have more to contribute to the franchise.
