My advice to first time filmmakers is believe in yourself and the message you want to give in the film you are making.

If you're making a film, the one thing I've learned is you have to pick somebody really well-known to make it relevant.

The link between Vreeland and Guggenheim is their mutual sense of reinvention and transformation. That made something click inside of me as I too reinvented myself when I began writing the book on Diana Vreeland .

I learned how to make a documentary by having a good team around me. My editors (and co-writers)Bent-Jorgen Perlmutt and Frédéric Tcheng were very helpful.

I think the most important is believing in yourself and being passionate about everything you do in life.

Research is fundamental; finding as much as you can and never giving up. I love the research. It is my "precise time". Not just for interviews but of footage, photographs never seen before. It is a painstaking process that satisfies me. The research never ends. I was still researching while I was promoting the Diana Vreeland book. I love reading books and going to original sources.
