Over 500 teams across the country will sweat, stress and eschew sleep this weekend in pursuit of making a short film in just 48 hours. The Vista Foundation 48Hours film festival is New Zealand's largest guerrilla filmmaking competition, running annually for 22 years. Teams of aspiring filmmakers, including school groups, families as well as professionals, are given a genre and a set of elements they must include in their final product. The rest is up to them. Todd Zaner dials up competitor Daniel Lynch in Wellington who, with his veteran team Cinetrance, is embarking on another weekend of intense filmmaking.
