Earlier this week, IGN.com has published an interview they did with Jessica in which she talks about Captain Marvel and The Martian:
Matt Damon is playing the lead in the film. And I’m playing an astronaut who tries to rescue him. I’m really excited to work with Ridley. I’ve always loved his work – ever since Alien with Ripley. He’s incredible and I love the worlds he creates. Also after I saw the film [Interstellar] I thought ‘Wow it’s such a great film – that would have been amazing – I want to wear wires now and be an astronaut.’ And then right after I saw it I got a call that said would I be interested in playing an astronaut. It happened all in line!
