Special behind-the-scenes edition of the nature show. Naomi Wilkinson reveals what really goes on during the making of Nightmares of Nature. From the dubious glamour of 'getting there' to battling with nature on location, nothing is without its challenges. She explains how the great British headlice were head-hunted for the UK show, and what happened when she tried to face her ultimate nemesis - the great white shark - whilst also giving viewers a glimpse of the shots both the crew and the animals wouldn't want anyone to see.
