In this episode, we talk to John Polson. You might know him from films such as The Sum of Us and, more recently, The Dry – or for the shows he’s directed including Elementary and The Walking Dead. But you might not know the remarkable story behind Tropfest – long described as the world’s biggest short film festival – which Polson founded and is bringing back after a six-year absence. Today he talks to Sydney Morning Herald senior writer Garry Maddox about the controversial highs and lows of the colourful festival, the high-profile team helping him revive it (from Bryan Brown to Sarah Murdoch), and how he landed Margot Robbie as jury president.
