In 1995, while sitting in a London pub, a bunch of men formed the first gay inclusive rugby club, the King's Cross Steelers.
Since then more than 60 clubs have formed around the world, facing off every two years to play for the Bingham Cup.
Eammon Ashton-Atkinson, an Australian news reporter living in New York, who was due to play himself until a concussion ruled him out, followed the Steelers on their journey to the competition.
The result is the documentary film Steelers: The World's First Gay Rugby Club which had its world cinema premiere in Auckland on Friday night, as part of Whānau Marama: New Zealand International Film Festival. Cinema screening details here.
