First Monday in May is the new film by Andrew Rossi. It is about the 2015 Met Ball Gala...you would have seen the images of THAT yellow dress by Guo Pei. The interview with Rossi ( he also did Page One: Inside The New York Times) is on RNZ National 101.4 FM (NZ) 9.40 am Sunday Morning. Podcast for an international audience after that.
UPDATE: listen to the interview.
