'The Prince's Rainforest Project' by Hurrell Moseley Dawson and Grimmer

Prince Charles and his sons, William and Harry pledge their support to preserving the world's rainforests, and urge others to do the same.

A line-up of famous faces, including the Dalai Lama and Robin Williams, as well as children from around the world, also lend their support to the campaign.

Each individual appears in the film with an animated frog - the symbol of the campaign.
