In 1996, two teams of climbers set of to conquer Mt Everest – and ended up fighting for their lives at 8800 metres in one of the fiercest snowstorms ever encountered by mankind.
Eight people would not return, including New Zealanders Rob Hall and Andy Harris.
The story had all the ingredients for a disaster movie, but creating a film set on the highest mountain in the world proved difficult.
It has been a labour of love for Working Title's co-chair Tim Bevan, who has been trying to get Everest off the ground for 15 years.
Story reporter Sarah Stewart went to meet the honorary Kiwi to find out what went on behind the scenes.
