Black Widow Movie
A Black Widow movie is a movie that is needed in the Marvel Cinemax Universe. With so many new Marvel movies coming out it's only fair that one of them is about a female superhero. And it's not just the fact that Natasha's a girl, she has an exciting backstory, a 'villain' turned 'hero'. Another reason why a Black Widow movie would be stunning is that with it we would get more of Clint Barton and an early form of S.H.I.E.L.D.
This movie would feature Natasha's training in the Red Room, why Clint recruited her, and Natasha transitioning from being a master assassin to becoming an agent of S.H.I.E.L.D. I forgot to mention Budapest, but Budapest has to happen in there somewhere.
Plus we would actally be able to find Natasha/Black Widow merchindice for once.
