Before they first boarded the Marvel Cinematic Universe, Joe and Anthony Russo were best known for their work on sitcoms Arrested Development and Community, with their last big screen effort being forgettable 2006 comedy You, Me and Dupree. It wasn’t like they were the obvious choice to step behind the camera for the first time in eight years at the helm of a $170 million comic book blockbuster, but Marvel’s gamble paid off pretty well in the end.
Not only have the siblings directed more movies in the MCU than anyone else, but they’re also responsible for the studio’s two highest-grossing installments, the latter of which became the biggest box office hit of all-time. Having got their start with the world’s most popular franchise on Captain America: The Winter Soldier though, it shouldn’t come as a surprise that Steve Rogers is the character closest to their hearts.
