Sienna Miller and Richard Curtis are among the judges of a new short film competition seeking to encourage young film-makers to produce "bankbuster" videos on issues being highlighted by the Robin Hood Tax campaign.
Applicants for the competition are being asked to make a 60- to 90-second video reflecting the aims of the campaign and inspiring others to sign up.
The Robin Hood Tax campaign is seeking to raise support for a levy on banks to tackle poverty and climate change in the UK and abroad.
Prizes include a masterclass with Curtis, the Four Weddings and a Funeral writer and director of Love Actually; being featured on YouTube's homepage; and camera equipment.
Miller said: "By making a film you are not just helping the campaign, you are joining a generation that has started to say enough is enough. We want to see your vision for the future, a future without poverty. The Robin Hood Tax is an idea whose time has come. Simply put – when governments tax the banks, they shouldn't forget the poor and the planet."
Curtis added: "We are looking for original and creative films that sell the idea of the Robin Hood Tax in new and exciting ways. We want anyone who watches the winning films to turn to the person next to them and say – 'I'm sure as hell supporting that!'"
The other judges are David Jones, chief executive of Euro RSCG Worldwide and Havas Worldwide; Andy Hobsbawm, co-founder of Dothegreenthing.com; John Jackson, vice president of social responsibility at MTV; and Mike Goodridge, editor of Screen International.
There will be a separate category for under 18s, launching via the Habbo Hotel website on Thursday, 3 June.
This category will be judged by actors Tom Felton (Harry Potter), Blake Harrison (The Inbetweeners) and Joe Dempsie (Skins).
