For Scarlett Johansson, 2014 is already off to a spectacular start. Her new movie, Her, with Joaquin Phoenix has been nominated for several awards and won the Golden Globe for Best Screenplay, and she’s just been named the first-ever Global Brand Ambassador for SodaStream. What’s next? A splashy Super Bowl ad.

“I’ve never done a Super Bowl commercial before and it’s a huge production,” Johansson shared with us. “I think the idea is that it’s supposed to feel like a big, eye-catching moment.”

We caught up with the 29-year-old actress about Her, wedding planning (she’s engaged to French journalist Romain Dauriac), and Avengers 2. “I feel really fortunate to have had this amazing year professionally,” she said.

What’s it like to have your film Her receive so much praise?

“It’s great when people like the work that you do. The experience making this film was such a different challenge for me because I came in during the post-production process. The work that I did with Spike and Joaquin was such an intimate, heightened kind of experience. It was just a totally different way of working. I wasn’t a part of the months of prep and all that stuff, so I didn’t know what the film really looked like. When I saw it all put together, the fact that it was cohesive and quite poignant, I felt really moved by it, that the relationship works, and that people respond to it—that was a gift more than any rewards or praise. The fact that the audience is responding to the relationship, that they get it, that’s cool.

“It’s heart-lifting, it’s heart wrenching, it’s a real study of a full relationship that is life-changing and grows. I think everybody can kind of watch it and think, ‘oh, I’ve had that conversation, that’s the worst feeling’ or ‘that’s so embarrassing’ or ‘I loved that moment.’ But then when it’s with a computer, it’s a whole other added thing.”

What was it like entering during the post-production phase? Did you still interact with Joaquin Phoenix?

“Yeah, he did a lot with me. We worked together extensively, which was very generous because he really had to do the movie twice. With [director Spike Jonze] we ended up recording the movie about 25 times. If nothing else, he’s extremely thorough. He never gives up until he’s exhausted every possibility and Joaquin was kind enough to go through that with me.”

You’ve done some voice acting in the past, but was it different lending your voice to something intangible?

“More than anything, the difficult part was that I never thought about her being this operating system. And of course she feels different, she has a different sensibility, things have a different type of meaning to her. The depth of her relationship, how you can love somebody, or how that can exist is different for her. She says that to Theodore, she says to him, ‘I can love you this way and you might not be able to love me this way because we’re different.’ So it was hard to wrap your head around what that meant because it kind of transcends what you know. It has an otherworldly sentiment.

“The way that she thinks and how she evolves kind of transcends time and space and expands. And that was kind of hard to imagine, but of course the core of Samantha is her enthusiasm at that expansion and that enthusiasm for everything. She’s excited about herself, her ability, and that she’s separate. She’s her own being. Once she realizes these feelings are separate from feelings that are programmed, that she can have her own feelings, she discovers that independence, she’s unstoppable. So that’s what I mostly focused on. The ‘how can she see him? She doesn’t have eyes?’ That kind of stuff. People can go in a tailspin about that.

Did knowing your character was also in relationships with other users of the operating system affect the way you portrayed Samantha?

“Well, I think again, her definition of a relationship and how it works and what can be acceptable is not the same. She doesn’t have the same standards, morals, or ethics. She doesn’t think in that way, she think by a different code of rules—or not. So that was just a part of who she is, she’s unapologetic about it and you have to kind of forgive her because you can’t hold her to the same standard as your boyfriend, it’s not the same.”

Have you talked to Siri about the movie and Samantha?

“No! But the other day Marcel [Pariseau, her rep] emailed me something ‘Siri doesn’t like Samantha’ or ‘Siri doesn’t like the movie’ or something, which is funny. I was like, ‘who programs it to be so topical?’ I thought about that. Did someone have to write that, how does that work? I don’t know. Do they have to come up with a strategy for how to answer that? Who’s the personality? I know the voice of the woman came out recently, but who’s the decision maker as to what kind of sass or whatever that Siri’s going to give you? I usually ask her things like, ‘do I look ok in this?’ She always responds, ‘you’re the fairest of them all,’ and I’m like, ‘I love you, Siri!’”

Do you think in the future operating systems could have relationships with people like in the movie?

“I don’t know, it’s so impossible to imagine. First of all, I’m so technologically impaired, it’s impossible for me to imagine anything past the fact that I can play tetris on my phone. I never think about artificial intelligence. Even in this film, it wasn’t really relevant to me because I wasn’t concerned with that part of it. I was really concerned with the relationship that these two characters were building. I hope in some ways that this trend we’re seeing in art and culture where people are starting to realize that there’s a kind of empty void that is filled by a lot of their devices, social media, and all of these ways that we’re connecting but we’re not. How can we return to the basics of communication, face-to-face and person-to-person? We’re missing that and I think we’re at a point where people are discussing that we’re missing that. I’m hoping that we return to humanity as opposed to putting a focus on creating an artificial intelligence. I try not to imagine the other end of it, that’s too doomsday.”

Have you started any plans for your wedding?

“No, I’m busy planning Avengers 2 right now! That’s my main focus. I’ve never been a big planning kind of person. I’d never share it with anybody, but I think more than anything I feel really fortunate to have had this amazing year professionally. And I think when all that smoke settles I’ll be able to … I don’t feel like I need to rush that part of my life. I can let that happen organically. Right now it feels like a time to enjoy and be relaxed and that’s what works for us.”

What can fans expect in Avengers 2?

“Oh boy! Well, we can expect the Avengers. Joss [Whedon], again, is back, wrote the script, and is directing. I think the script is dark and it’s dry, it’s got this amazing one-liner, glass-cutting sense of humor. Obviously the script is very cerebral. It doesn’t lose that exciting comic book aspect that people enjoyed in the first film, but it’s smart and it feels like the next installment. It doesn’t feel like a rehashing, it feels like these characters are moving forward, plotlines are moving forward. It’s deep and I think that’s why people really respond to the Marvel universe, because the films are fun and exciting and have all that flashy stuff, but there’s a gravity to them. People can expect that gravity this time around.”

What can viewers expect in your new commercial for SodaStream?

“Well it is a Super Bowl commercial, so it’s flashy and the product is fun. Of course it’s bubbly, so they wanted to kind of get that across. I’ve never done a Super Bowl commercial before and it’s a huge production. I think the idea is that it’s supposed to feel like a big, eye-catching moment. You want to make sure that people understand the environmental benefits, health benefits, lifestyle benefits in a 30 second spot. It’s a lot of information, plus the eye-catching part to capture.”

What are your Super Bowl plans?

“I only recently started to understand how you play football. I’m a baseball fan, that makes sense in my mind, I understand the rules; to me football has always looked like a bunch of people running. It’s only the past couple of years that I started going to Super Bowl parties and getting enthusiastic about it. It’s the buffalo wing championship that I’ve started with my friends that keeps me coming back. It’s delicious and there’s a lot of pride with the wings. I won last year.”
