Black Widow's Support
To be honest we never thought a solo Black Widow movie was going to happen but the success of Black Panther and Captain Marvel has definitely convinced Marvel Studios that the future is with diversity (It took them long enough and will be embarassing forever that they couldn't be bothered to risk a female superhero until after DC proved the 'no-duh' appeal of female leads via Wonder Woman). Regardless of their motivations and sluggishness the Black Widow standalone is definitely on the fast-track now with new casting announcements.
So far we've got the always reliable David Harbour (thank god that Stranger Things woke people up to his talent!), the fast-rising Florence Pugh (so excellent in Lady Macbeth two years back and currently headlining Fighting With My Family), and there are rumors that Rachel Weisz is also coming on board. The cast sounds very promising...
