Home Movie Day, a celebration of amateur films and filmmaking held annually at many local venues worldwide, is Saturday October 18, 2008. 

Home Movie Day events provide the opportunity for individuals and families to see and share their own home movies with an audience of their community, and to see their neighbors’ in turn. It’s a chance to discover why to care about these films and to learn how best to care for them.

Information on events around the world is available at the HMD site.
