Tropfest Short Film is an experimental film festival and art exhibition that was started in Sydney, Australia more than 20 years ago. Last year, New York’s first Tropfest took place in Bryant Park, and it’s hopping across the East River to Prospect Park for 2013. The festival attracts submissions from established and emerging directors and writers alike, including Australian actors Sam Worthington from Avatar and Joel Edgerton, who plays Tom Buchanan in fellow Aussie Baz Luhrmann’s The Great Gatsby. The films cover every subject imaginable. The only requirements are that they be created specifically for the festival; run no longer than seven minutes; and in some way incorporate that year’s Tropfest signature item–this year it’s bridges. Tickets are free when you RSVP here.
