Scarlett Johansson’s having a minor McConaissance just now. Lucy earned over $200 million worldwide, the highest-grossing action blockbuster not based on a comic book or a Hunger Games ripoff or an action figure–which is a roundabout way of saying that it probably earned that money because people wanted to see Scarlett Johansson. Lucy comes on the heels of major roles in acclaimed low-budgeters Her and Under the Skin, plus a co-lead role in Captain America: The Winter Soldier. Cap 2 marked her third go-round as Black Widow, a character who would seem ready-made for her own spinoff even if she weren’t played by one of the most recognizable stars in Hollywood.

But Black Widow: The Movie appears to be a distant prospect right now—Marvel head honcho Kevin Feige described the possibility of a female-led Marvel movie as something that would happen “sooner rather than later,” which is another way of saying “not right now.”

Too bad, because he might already have a good director: Neil Marshall.

The filmmaker is best known for helming the Game of Thrones megasodes “Blackwater” and “The Watchers on the Wall,” but in film-nerd circles, he’s a minor god for 2005’s The Descent, a tense and gory action-horror treat starring a (basically) all-female cast.

In an interview with Vanity Fair, Marshall mentions how much he enjoyed Lucy, and says, “I’d love to do a big splashy movie with a great female lead.” When asked if he’d be interested in a Black Widow movie, Marshall excitably responds:

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.

Any movement on a Black Widow spinoff is probably on hold just now, while Johansson caps off her busy year by giving birth to a new human being. Still, Marshall is the kind of journeyman director that Marvel likes to hire–recall that fellow Game of Thrones alumnus Alan Taylor handled Thor: The Dark World. You can read the full interview over at Vanity Fair, and start fantasy-casting Game of Thrones actors in lead Black Widow roles. Like, Nikolaj Coster-Waldau = Red Guardian, maybe?
