This climate change film weaves together a bold new speech from JFK, Churchill, Mother Teresa and others

A new climate change-focused film from New Zealand's Energy Efficiency Conservation Authority creates a new speech by weaving together the words of 23 inspiring figures from the past.

JFK, Winston Churchill, Mother Teresa, Einstein, Gandhi, Anne Frank, Stephen Hawking and Nelson Mandela are among those whose words feature in the film, by Clemenger BBDO, which urges people to think about the climate and conserve energy.

The campaign is called "Generation Less," or Gen Less, and according to Brigid Alkema, executive creative director at Clemenger BBDO, it's united around a central thought: “It takes all of us, a generation, to ignite real change. Those in Gen Less are united not by their age, but by their collective decision to embrace a life with fewer emissions from energy."

In the process of putting it together, the agency had to deal with many of the estates of figures in the film. It also conducted extensive research on hundreds of speeches and interviews, from well-known speeches to little-seen archival footage. The ultimate figures and quotes were chosen to reflect "a diversity of thought, cultures, backgrounds and beliefs that represent people from all walks of life." The clips were pieced together by animation house Assembly.
