The 27-year-old actress, who played the gun-wielding hero in the film, said she and Marvel Studios have 'spoken a lot' about developing a film that follows the heroine's origin in Russia, reported Ace Showbiz.
"I love her origin story. I think it's just such a riveting one. It's just steeped in history and the richness to shoot in Russia, perhaps... I hope that the fans' voice is loud enough and they want to see a Widow origin story, I know Marvel would be happy to entertain that. We've spoken a lot about it," she said.
Johansson also dished on what is the difference between playing Natasha Romanoff in "Iron Man 2" and "Avengers".
"In 'Avengers' you see a little bit about how Natasha joined and it's not that she's fighting for the greater good of humanity. She was almost salvaged by SHIELD and so she's loyal to that group, to that agency, but only as sort of paid debt," she added.
