When I graduated from Brown after majoring in women's studies, I made my first PBS documentary, 'Women of Substance.' My first feature documentary was called 'American Hollow,' which I did for HBO and was at the Sundance Film Festival.

I've always been interested in Vietnam, feel it's a seminal event in our nation's history, and have explored it over the years - but I hadn't been interested in doing a documentary about it. I felt there had been a lot done about Vietnam, and didn't know if I could add anything new to the discussion.

I've been doing documentaries for about 25 years and want to continue to do that, but I love the idea of working in a different medium. Advertising pushes the envelope creatively, and there is some really great work being done right now, so I'm excited to jump into it.
