Marvel Studios has always faced obstacles, but the last few years after the Infinity Saga have presented some major uphill climbs. The shocking death of Chadwick Boseman caused Marvel Studios and director Ryan Coogler to restructure Black Panther: Wakanda Forever and likely other plans for the Marvel Cinematic Universe. Like so many others, the studio also had to deal with a pandemic that altered the rollout for its next saga. Marvel Studios also isn't as successful as it once was, with various box office bombs and critical failures that would've been unheard of before and the WGA and SAG-Aftra strikes this year paused development for months. Now, Marvel Studios has moved on from Jonathan Majors after being found guilty of third-degree reckless assault and harassment.
