Initially it was assumed that in the solo film about the Black Widow, the action will unfold before Natasha Romanofoff left Russia and joined the shield and Nick Fury. Marvel star Sebastian Stan, who, according to rumors, in the "Solnik" of the Black Widow will be assigned some role, not so long ago in Italy and, during communication with local fans, said that the action in the film will occur immediately after the events of the "first Avenger: confrontation. "
The "confrontation" ended in that Steve Rogers went to resolve those who supported his Avengers in Raft and, together with them, hid from the authorities in Vacante - the fate of Natasha at that time was unknown. This leaves the spacers space for maneuver - perhaps the film will be shown than the black widow did after the Iron Man and Captain America quarreled, but before RomanoNoff joined Steve Rogers and other avengers in the "Infinity War".
So far no official information about the film - in addition to the name of the main star, the director and the screenwriter - no, and what will happen from the attempt to provide the Solnik's widow, we will find out in May 2020.
