"Willa Holland: Most of the time you've just got to sit back and watch John do John 'cause it's just one of the most amazing things you could ever witness in your life. And then a lot of times he brings you into it and you can't say no. It's kind of 50/50 at the end of each take. But regardless, every time we work together it's pretty hard to focus on the job at hand. For example, when we were shooting the scene where I actually was shooting him, we did a few rehearsals and I can't remember exactly what he was doing but it was kind of the look on his face and just this weird smile that he would give to me and I just could not take it seriously. It's kind of amazing. I mean, just picture John."
