Harrison Ford and other stars feature in the rainforest film
An array of celebrities have appeared alongside Prince Charles and an animated frog in a film to highlight the dangers of deforestation.
The stars, including actor Harrison Ford and football legend Pele, appear in the video to pledge their support to the Prince's Rainforest Project (PRP).
Viewers of the online 90-second film are being encouraged to sign-up to the project's "rainforest SOS" campaign.
The prince said he hoped it would build an online community calling for action.
Other famous faces appearing in the film include James Bond actor Daniel Craig, comedian Robin Williams, as well as the Prince of Wales's sons, Princes William and Harry.
"What happens in the rainforest has an immediate and powerful effect on our lives," explained actor and long-time environmental campaigner Harrison Ford.
The "frog and prince" theme was welcomed by Prince Charles
"The air we breathe, the clean air that's required, the services that ecosystems provide are beyond value," he added.
"I believe it is our moral responsibility to protect the environment, to save what we can of the planet's resources for future generations and our children."
The Hollywood star is featured in the film pledging his support, while a computer-generated frog sits on his shoulder.
Briony Mathieson, head of communications for the Prince's Rainforest Project, explained the idea behind why a frog featured in the film.
"There were a number of reasons why we really liked the 'frog and prince' concept," she said.
"Firstly, it is a fantastic symbol for the rainforest, and it is also an indicator species for climate change."
Ms Mathieson said that the Rainforest SOS website would also have online editing software, allowing people to make their own "mash-up" version of the film in which they could appear alongside the frog and celebrities, and then upload it on to the web.
