Problem is Johnny Depp is white. As is Ezra Miller.
There are different rules for white people and black people.
Majors being dropped from both his Management AND PR Firm indicates a lack of support and without that support a blackballed black actor has an infinitely steeper hill to climb. It honestly might be impossible
Tbh Depp is still pretty blackballed in Hollywood.
His last two projects were him voicing a puffin in a cheap UK animation show and a French arthouse movie. Other than that he has nothing else lined up.
Ezra will have the same fate once the Flash is out and has made its money. WB doesn't want to pull the trigger as he'll be needed for light very controlled PR.
In fact that scenario may save Majors. I'm guessing because Majors is so pivotal to Loki Season 2 firing him now kinda messes up a ton of shyt. If this story goes away he may just ride this out with a forgiveness tour.
But you bet Marvel has a list of actors ready to go in case any crazy video is revealed or charges are filed.
Also, The Josh Brolin story may give them pause to fire majors for something another one of your actors was also accused of doing multiple times.
