Today, with their story almost forgotten, only five of these heroic players remain alive. We have interviewed all of them and left no stone unturned in the search for photographs, memorabilia and moving images associated with their triumphs to bring vividly to life once more the glory of those far-off years.
And now we need your help.
The documentary will be screened as part of this year's 15th Belfast Film Festival. However, we have included lots of fantastic archive footage and photographs which need to be paid for, some of which, from the World Cup itself, are particularly costly.
We need £13,500 to pay for clearance rights to show this documentary at festivals around the world and once more shine a spotlight on the achievements of this remarkable team.
Whether you're a fan of the Northern Ireland team wanting to see for the first time a forgotten segment of their history or a fan of archive-based documentary making you can make a difference. We have the platform to screen this film in place and now all we need are the crucial funds to clear the wonderful archive we have spent so much time uncovering. We want to share this fantastic story with sports fans in Northern Ireland and around the world but it can't happen without your help.
Please visit the "Spirit of 58" crowd funding page and help to share this documentary with the world.
