Marvel Studios are planning a movie based on Scarlett Johansson's Black Widow character.

The 29-year-old actress first portrayed the popular Marvel comic book character - who is also known as Natasha Romanoff - in 2010's 'Iron Man 2' before reprising her role in 2012's 'The Avengers', and is once again set to hit the big screen as the superhero in 'Captain America 2: The Winter Soldier' and 'The Avengers 2: Age of Ultron'.

President Kevin Feige confirmed the prospect of a solo film since audiences still have more to learn about Johansson's alter-ego.

Talking to Total Film magazine about the forthcoming films which feature Black Widow, he said: ''We learn more about her past and learn more about where she came from and how she became in that film.

''The notion of exploring that even further in her own film would be great, and we have some development work with that.''

Johansson thinks a Black Widow film would be ''totally awesome'' and insists it would be different to the other comic book films which have already been released.

The Hollywood beauty previously said: ''I personally think there's an awesome Black Widow movie in there. A kind of 'Bourne' film that would take the whole comic book genre in a completely different direction. It'd be awesome.

''I've spoken to Marvel about it and Kevin Feige, and there's so much story to draw from, I think it'd be totally awesome.''
