His numerous credits include the BAFTA award-winning film Touching the Void. Between 1980 and 2008, he co-directed the Kendal Mountain Film Festival of which he is a founder. Brian and his wife, Louise, divide their time between the UK’s Peak District and New Zealand’s Southern Alps. High Risk is his first book.
