"Civil War's" Russos, Olsen, Bettany Play Matchmaker With Vision & Scarlet Witch

Ever since the formation of the big screen Avengers in 2012, fans of the source material have wondered if the Marvel Cinematic Universe might eventually explore one of the team's most prominent romances. The movie version of that romance stepped closer to reality when Scarlet Witch and the Vision debuted in 2015's "Avengers: Age of Ultron." The characters have been the Avengers' first couple for decades, even going so far as to get married and have children.

The characters, played by Elizabeth Olsen and Paul Bettany, play a part in "Captain America: Civil War," where they're members of Team Cap and Team Iron Man, respectively. After a furtive glance or two in "Avengers: Age of Ultron," the superheroic couple may be inching closer to a love connection in the new film -- while also being pitted against each other in the superhero civil war. During the press tour for the latest Marvel Studios epic, filmmakers Anthony and Joe Russo and actors Elizabeth Olsen and Paul Bettany spoke about the pair's onscreen dynamic and expressed their interest in seeing how the two characters evolve and interact. And be warned -- some possible, light spoilers lurk ahead.

Anthony Russo: We looked for opportunities in the movie to play with these rich, complicated relationships. There's a very interesting relationship between Scarlet Witch and Vision that begins to develop into an interesting, complicated relationship. To put them on opposite sides in the battle was very exciting to us because it sort of interfered with what was happening, the dynamic between these characters and watching these characters and watching them push that forward.

Paul Bettany: It was a really interesting idea: you find Vision in "Age of Ultron," he is just born and omnipotent, yet naive. Then in this movie, you find him trying to figure out what humanity is, and how you have loyalty, because logic doesn't afford loyalty. So I think it's really interested in working out what love is.

Elizabeth Olsen: I think what ends up happening is she was starting to feel confident, but it wasn't about her powers. It was more about the conflict she had with making a big mistake. I think what's interesting is every superhero has a weakness, and I've always thought of hers as she's the person who gets in her way, and she's kind of limitless. So that's, to me, an interesting character trait.

Paul Bettany: There's this woman [Scarlet Witch] who has a similar problem that she's facing, which he doesn't know the limits of his power, and nor does she. Of course, love can make you feel loyal, and at the end of this movie, and I think it's a double-edged sword because you see his response of finally having a human response is he makes a big mistake, which is interesting, and I thought was a really deft piece of storytelling.

Elizabeth Olsen: I don't know what we're going to do next, but I think of her as being an incredibly strong, powerful person. And it's also fun because I feel like she could flip either way because of her mind...I think this film was a lot about just conflict in general of what's right. How do use your abilities, or whether you should or not. I think that was a consistent theme throughout the whole film. I think it consists of that as opposed to her being not confident.

Joe Russo: She is in a growth arc. It is part of her development. It's very tricky with very powerful characters, because unless they have an internal struggle or a flaw that limits them, then they do become limitless and then the storytelling becomes muddled and not very interesting. She could have stopped that flight at the airport in five seconds if she were at the peak of her powers. So it really has to do with her character specifically going on a journey to understand what the limits of her powers are, makes a mistake very early in the movie that sets her back. We'll get to see where she goes in "Infinity War."

Anthony Russo: For us, that's the heart of any conflict in the movie, whether it be a dramatic conflict, or an action conflict. That's what you run at.

Directed by Joe and Anthony Russo and starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Anthony Mackie, Sebastian Stan and more, "Captain America: Civil War" opens on May 6.
