Joe and Anthony Russo directed the highest-grossing film ever, Avengers: Endgame, for Marvel Studios but nearly quit their association with the Marvel Universe over an argument regarding Captain America: Civil War. The new book The Story of Marvel Studios: The Making of the Marvel Cinematic Universe details a breakdown in the relationship between Kevin Feige’s Marvel Studios and the Marvel Creative Committee stationed at Marvel Entertainment’s headquarters in New York City. After directing Captain America: The Winter Soldier, the Russos wanted to bring something new to the big screen or their second Marvel effort. That meant sowing conflict within the Avengers, bringing Captain America and Iron Man to blows as in the Civil War comic book event. The Creative Committee vetoed the idea, insisting the Avengers reunite to fight Baron Zemo and his squad of super soldiers in the film’s final act.
