I find in most cases, especially on film, the actors are in a trailer, you come up to set, rehearse, you leave, they light. So it's like the crew and the actors are separate.

And then you come and everyone's kind of doing their thing. They do the scene and it's like, 'I'm the actor, watch me. Film me.' With a Terrence Malick film it's the opposite. There's no trailers and I would get my pages, memorise my dialogue, and I could say it in any order.

- So you had a lot of freedom?

Yes, and for me the most challenging thing, and the greatest lesson of this, was about not planning anything.

- What's your favourite line in The Tree of Life?

It's actually in the trailer: 'Unless you love your life will pass by.'

- What does that mean to you? 

If you don't fully take every moment and love every moment and every person that you're with, your life will be over before you realise. You will have spent like 80 years of your life without living. To me it's a beautiful thought.

- Is it true that Terrence kept calling you back to do more voice work after the completion of filming, three years ago?

Yeah. I'd be on sets or even up at Thanksgiving with my family and I would get a call asking me to put some stuff on tape, which of course I was very happy to do, and I would get a FedEx with 30 pages.

I would go into a sound booth with someone who had no idea who I was or what I was there for or what the movie was, and I would just whisper these lines. Most of it has not made the film, but I loved it. Maybe because I came from the theatre I loved the idea of a collaboration, and I like not having a timeline.

- Do you prefer being on stage?

It depends. I started on stage, so for me it's what the character is. Two years ago I did Othello, I played Desdamona and Phillip Seymour Hoffman was Iago, in a theatre that was 1400 seats, and that actually made me realise I don't prefer that, because in a theatre that big someone is so far away from you, it makes it more difficult to have honest reactions because you have to project.

You can feel it, but you have to like show that you're feeling it. I like just being in the moment and working with the same partner. I prefer small theatres when I'm doing theatre, but it's all about the part. So the part could be television, theatre, cinema.

- Was there a scene in The Tree of Life that was particulalrly difficult?

In a Terrence Malick movie you don't film in scenes. There is a section of the film that deals with grief, so we spent about a week-solid shooting, which means that you shoot all day and the only break that you have is the two minutes to reload the camera.

It's not like, 'This is the scene, beginning, end.' It's more like, 'Okay, this is what we want to convey. Here's some lines. Let's try it here, but it's grief. Okay, now I'm going to give you more lines. Let's try it outside.' So it's like a week and a half of those emotions, and that was challenging.

- You've done a second film with Terrence, The Burial, starring Javier Bardem, Ben Affleck, Rachel McAdams and Rachel Weisz. Who did you work with most on the film?

All my scenes are with Ben Affleck, but I was only there for a few days and for me it was more of an opportunity to go and see the entire crew and Terry and visit the set.

So I don't know whether I will be in that movie. Probably I won't make the end of it. But for me that was more about the experience of being with everyone again.

- You've made 11 films in four years, but you're still really at the start of your film career. How does it feel to have worked with one of contemporary cinema's most respected filmmakers, at such an early stage?

It's a very strange feeling to have had possibly one of the greatest experiences of your life right at the beginning. Meeting him and making the movie [The Tree of Life], every day I felt like, This is it, I've arrived.

This is beyond anything I'd ever imagined.' And then I saw the movie and I was like, 'Yes!' It just lived up to everything I had wanted. So now it's what do I do now?

The Tree of Life is out 8 July in cinemas across the UK
