Well, she actually didn’t get blackballed or blacklisted by Hollywood. Yes, she did kinda get dropped in the third Thor movie, but so too was Natalie Portman. And, she didn’t get blackballed by anyone, even after some of her private pictures were despicably leaked online.
If you look at her filmography, she’s been doing well in terms of her television appearances, with recurring voice and acting roles in shows. And of course, she’s back to the MCU too with her role in WandaVision. So, I think that we may well see her in the next Thor movies, especially after Natalie Portman becomes Thor in them.
So, while she has done more television work than feature film work; that does not suggest that she was blackballed by Hollywood.
