Given a totally ambiguous script, a bunch of directors and actors split into groups and went off to shoot a story of their own creation. The only rule: use the dialog in the generic script.
Here are some directed by Sean Donnelly (I'd be happy to post other directors' open scenes here too -- directors please email me).
