Shailene Woodley stars in Divergent
Woodley was being interviewed by Collider, when she explained, "Green screen acting is, by far, way more difficult than human interaction. It was a big learning lesson, on this movie. It was really fun. I’ve never done a movie of this scale before, with themes this big and a world that’s completely different from the world that we live in today."
She added, "So, a lot of it was challenging for me because I had to erase my preconceived notions of what I was used to, acting in movies, which is generally reacting off of somebody else and creating a new world, and adapt my style of artistry to the style that this movie lent itself to. It was really exciting Veronica created such an amazing world, and then Neil visually brought it to fruition in a way that I could have never imagined it. We’re so lucky to be pieces in the puzzle of this dystopian future."
