Making a film for a green cause requires an imagination…and talent. Long before it became common practice to crowdsource for talent online, we tapped social media to invite filmmakers around the world to enter Rain Bird’s Intelligent Use Of Water competition for the best short films that would portray the urgency of the global water scarcity issue. The experiential campaign included a microsite and digital communications to engage Millennials on Twitter, Facebook and MySpace. We tapped into online forums for filmmakers. Grassroots efforts included street teams sent to 40 schools nationally to promote the competition to students, film professors, and with the American Film Institute and American Cinema Foundation. We received 87 film entries in three months, showed finalist films at a guest-only LA event and awarded monetary prizes for top winners.
