Scarlett Johansson made her debut in the Marvel Cinematic Universe five years ago by taking on the role of Natasha Romanoff, a.k.a. Black Widow in 2010's Iron Man 2. Since then, she has quickly become a fan favorite, appearing in Marvel's The Avengers, Captain America: The Winter Soldier and next month's Avengers: Age of Ultron. There has been talk over the years about a potential Black Widow stand alone movie, but when Marvel announced their massive nine-movie Phase Three slate back in October, a Black Widow movie was nowhere to be found. While promoting Avengers: Age of Ultron last weekend, Scarlett Johansson revealed that she has actually discussed a series of Black Widow movies with producer Kevin Feige.

"I've spoken to Kevin about it. I mean, of course, of course we've had that conversation before, and I think Kevin would also like to see a standalone film. I think I can speak for him and say that. That's all, really. Right now I think this character is used well in this part of the universe, but I think that Kevin - I mean, we've talked about it and we both share similar vision for what could be a standalone series."

The actress added that she thinks there is room in the Marvel universe for a Black Widow movie, but it isn't clear when that may come to fruition.

"I think that there's room for a standalone movie. The character has a really rich origin story and I've been really fortunate to kind of place all these layers on top of one another and kind of build up this character to this point where I think I can now start to peel them away and reveal different sides of her and really focus on-I think I've been able to grow with the character, the character's been able to grow with me. Her dilemma that she faces it's a deeply personal one, she has this great, huge, epic kind of calling and now is suddenly going, 'Wait a minute. I have this epic calling, but I wanna make a choice for myself. I feel like I've put in the hours, I should be able to make active choices' and she inevitably chooses the heroic path and kind of puts her own personal desires and needs aside. Those are things that kind of butt up against each other and interesting things happen when you have a character that's pulled in many different directions and in my mind there's room for plenty more Black Widow and certainly more-I think I could see her in a standalone film."

The actress also talked about how her initial contract with Marvel has changed, since the studio was unsure how the fans would react to her character, and that she originally wasn't set to be a part of Captain America: The Winter Soldier and the upcoming Captain America: Civil War.

"My contract has changed. Marvel and myself didn't really know how the fans were gonna react to Black Widow the first time and how she was gonna be-they couldn't anticipate how they would want to use her or if they would want to use her. I mean we invested in that character, but the audience had a great reaction to the character, which has been so awesome. For instance, I wasn't contracted into doing Cap movies, but that storyline worked out so well I kind of branched off and I found myself in that standalone movie. My contract is kind of mutating, I guess [laughs] or morphed to fit the demand of the character."

Scarlett Johansson adds that she has a very good relationship with the studio, and she will certainly be sticking around for quite some time.

"It's been a very good relationship back and forth and I think Marvel-the one thing about working with them is they don't want anybody to work on the movie that doesn't want to be there, obviously. So whatever you're contracted to should not feel like golden handcuffs, and they don't want that either... I will certainly be around and that's because it's been such a great response. I mean, I'm always happy to put the cat suit back on, for sure."
