For me, moving from photography to film was very easy.

I remember when we were at Sundance, we were in Robert Redford's screening room, and I had never seen the film look so beautiful or sound so great. It was really big and really powerful, and I had a sense of accomplishment in finishing a project like this.

We just grew to trust each other [with Patti Smith] more and more over the years. Most of the time I didn't even have a movie camera.

I think those moments in Patti's [Smith] bedroom really helped the film [Dream of Life] out, and those moments existed because of the trust between us. There isn't any real self-consciousness in the film because we all like each other.

I do remember, the first time we met [with Patti Smith], the door opening with a squeak. And then there was this very beautiful girl looking out.

For me to see the film [Dream of Life] on a big screen - it's pretty extraordinary.
