The Universal Scream project began as a promise I made to my then six-year-old daughter that I would photograph her favourite toy with children I met around the Pacific Rim during my yearlong journey with Michael Palin for his travel series Full Circle. 

The toy in question was a five-foot tall inflatable doll based on Norwegian artist Edvard Munch’s painting The Scream of Nature and the first pictures were taken with a group of Inuit children on Little Diomede Island in the Bering Straits in August 1995. 

Eighteen years have passed and my daughter Sonia is now almost 25, but a version of the inflatable Scream still travels with me - and I continue to photograph it whenever I get a chance. 

From the Sahara to the Himalayas, with novice Buddhist monks in Bhutan to Yanomami warriors in Amazonia, the doll has been photographed in hundreds of locations with a cast of thousands from all around the world.
