From the moment that Scarlett Johansson first appeared on the big screen as Black Widow in the Marvel Cinematic Universe, there have been fans all over the world who have called for the actress and the character to get their own movie. With Marvel having so many new movie projects lined up for the coming years, it looks highly unlikely that we will ever see a Black Widow standalone film.
With that in mind, fans have suggested that a good way to go would be to bring us a Black Widow and Hawkeye series on Netflix, although it is highly unlikely that we would see Scarlett Johansson or Jeremy Renner wanting to do a full series. So now it looks like there has been another idea that has been mentioned and, rather than coming from a fan, it has come from a Marvel hero.
Actor Charlie Cox plays the role of Daredevil in the hit Netflix series and he has admitted that he thinks it would be a great idea to have Scarlett Johansson as Black Widow on the show, even if it is just for one episode. With Black WIdow and Daredevil having some history in the Marvel comics, it would make perfect sense for it to happen and, if it was only for the odd episode here and there, then maybe Scarlett could be talked into it.
For now though, there are no official plans to have Scarlett Johansson appearing as Black Widow in the Daredevil Netflix series, so we will just have to make do with seeing her in the upcoming Avengers movies instead.
