But for the Russo brothers, it also raised a question that would be familiar to the superheroes of Avengers: Endgame — what to do next with all that power?
The brothers did not spend their many Marvel promotional world tours just taking endless selfies with hysterical comic-book fans, but searching for new avenues to explore, they said.
The result is a notably international and political slate of projects for their new studio AGBO — and barely a spandex-clad superhero in sight.
But politics is a common thread to the brothers’ next projects, which include a film about the opioid epidemic in their home state of Ohio.
The brothers are not committed to any future Marvel films, but their desire to import new perspectives to Hollywood filmmaking is already apparent in the Disney-owned franchise’s next projects.
Ms Marvel will soon become Marvel’s first on-screen Muslim superhero, with a TV series on Disney+ streaming service about a Pakistani-origin teenage girl living in New Jersey.
According to Joe, Marvel Studios boss Kevin Feige is “expending a lot of energy to diversify the Marvel Universe because everyone has the right to see their stories on screen”.
