Remember the explosive "Blackwater" episode of 'Game of Thrones' season 2, where the quick-witted Tyrion used wildfire to engulf nearly all of the enemy's fleet in a mushroom cloud of green flame? Or how about the second-to-last episode of last season, "Watchers on the Wall," which had giants, war mammoths a crazy single-shot scene? Director Neil Marshall is the man behind those iconic installments, but could he be returning to the big screen next to make that Black Widow movie everyone keeps talking about?

Fans have been pining for a solo Black Widow movie ever since they saw Scarlett Johansson kick some major Chitauri ass in 'The Avengers' -- and she did so without any superpowers. The problem is, while 'Guardians of the Galaxy' writer Nicole Perlman did confirm she had worked on a script for such a project way back when, a solo outing for Natasha Romanoff is not on Marvel's list of priorities. Still, if anyone is to direct the film in the future, Neil Marshall wants to be the man to do it. He doesn't have 'Game of Thrones' season 5 to worry about, so...

Speaking with Vanity Fair, the Marshall said in response to a potential Black Widow movie:

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.

Marvel Studios President Kevin Feige gave fans hope when he said recently that his team has plans to make the cinematic universe more diverse, though we're likely to get a solo movie for Captain Marvel before Black Widow, as the former is rumored to make an appearance in some capacity in the upcoming 'Avengers 2,' while the latter played a major role in 'Captain America 2.' "Frankly if we do a Black Widow movie after 'Age of Ultron,' when she’s been central in three or four movies, I don’t think we’d get the quote unquote credit for it," said Feige previously to Badass Digest. "People would say, ‘She’s already a big giant superhero!’ But if we had a great idea, we’d do it."

The next time we see Black Widow will be in 'Avengers 2,' hitting theaters May 1, 2015, where she'll be tackling the sentient robot Ultron, and "The Twins" Scarlet Witch and Quicksilver, alongside her Avengers buddies. Marvel, also, set aside a ton more release dates for unannounced films all the way through 2019, so perhaps one of them will end up being a solo Black Widow film, or at least one with a leading female role.
