The British Film Institute has recently begun a campaign to restore nine silent films by Alfred Hitchcock. These films represent his earliest work, and they are deteriorating after years of use. BFI has set up a webpage seeking donations, asking movie geeks of the world to adopt one of these legendary works and save them from wearing away.
As with all things philanthropic, they are looking for large donations, but they also have an option to select the amount you want to give. Please remember that the donations are in British Pounds, so for every pound you give, you are giving around a buck and a half. Still, the end result will be the preservation of some very important cinema.
