According to Cinema Blend on Monday, director of "Game of Throne's" Neil Marshall is indeed anxious to helm a solo "Black Widow" movie. Apparently, there's a demand for female-lead/solo movies featuring women and the director does indeed seem "hot to trot" to take command of a solo female film. For clarification, the director did mention it wasn't entirely relevant to him whether or not the leading lady in question would need to be a super hero.
In fact, he did draw an analogy of what he did desire, and ironically he had chosen the Lucy character in the movie "Lucy" that stars Scarlett Johansson. He feels he cannot relate to those that have super powers because they are indestructible and less believable. He proclaimed if someone with powers and special abilities do die, they wind up coming back to live later on. Marshall just feels he has to believe strongly in the character in order for it to be convincing.
The reporter that did the interview decided to draw Johansson's mention by Marshall into her Black Widow's character's "ties." The director thrillingly responded that he'd love to do a solo "Black Widow" movie. It seems by painting a picture first to the director and tying it in to other attributes between the actor, character, and story, there could be an exception made. After all, Agent Natalia Romanoff has no powers whatsoever, just honest to goodness hand-to-hand combat and weaponry training.
"I would love to do a Black Widow movie. That’s perfect. I would love to do that. That character is really interesting, she doesn’t have any superpowers, she just has extraordinary skills, and the world that she comes from, being this ex-K.G.B. assassin, I find that really fascinating, yeah. I’d love to do a big splashy movie with a great female lead, but it has to be someone I can believe in."
It may be even though of that Marshall may figure this to be more of a spy/espionage-like character synonymous to the Tom Clancy series of novels. The "Game of Thrones" director gives unto the Black Widow character a distillation of her relationship with her cohorts, her darkness and wit, sex appeal, skills and prowess, all of which leads to a rather in-depth and involved character that some may wonder why someone has not given the green light to get the ball rolling on a "Black Widow" film. Perhaps even a "Marvel One-Shot" is due once again, but that's just mere speculation.
