London, Nov 1 (IANS) Oscar winning filmmaker Danny Boyle says he was left so traumatised after camping that he has decided never to go for it again.

The filmmaker spent six nights sleeping outdoors at Bluejohn Canyon in Utah while researching for his next project ‘127 Hours’, about the real life story of Aron Ralston. While camping, he was trapped by a fallen boulder.

The filmmaker says he’ll never repeat the experience, contactmusic.com reports. ‘We camped out in the canyon for six days. It had been 30 years since I’d been camping — and it’ll be another 30 years before I do it again.’
