New reports indicate that the filming start date for Marvel Studios' Black Widow has been pushed back from late February/early March to June.

An official cause for the delay, which was first reported by Pursue News, has not yet been released. So far, all we know about Black Widow is that it will focus on Scarlett Johansson's past as a Russian spy defecting to America, where she eventually ends up working for S.H.I.E.L.D.

Production locations have been reported previously, with Croatia and Miami said to be on the docket, as well as the United Kingdom, which would see Natasha Romanoff's adventures following in the vein of other Marvel Cinematic Universe movies filmed in the United Kingdom, such as Spider-Man: Far From Home, Doctor Strange and Guardians of the Galaxy.

While this schedule gets ironed out, one thing fans will be keeping an eye on is if the movie does indeed end up being R-rated. Disney CEO Bob Iger recently doubled down on his interest in making mature, adult-oriented movies, so there is a slight chance we will see Black Widow deploy some overly violent moves as she fills up that famous red ledger we first found about in 2012's The Avengers.

Black Widow is set to be directed by Cate Shortland (Berlin Syndrome) from a script by Jac Schaeffer (TiMER). The film will see Scarlett Johansson reprise her role as Natasha Romanoff/Black Widow and is expected to be a prequel, much like Captain Marvel. While an official release date has not yet been announced, Black Widow is rumored to hit the big screen on May 1, 2020.
