Tales from the wild

'We worked with a lot of Inuit, and when we first began filming they wanted to tie a rope around [cameraman Adam Ravetch] while he was shooting underwater. When I asked why, they said that was the only way we would get his body back. They told us that walruses can hold a man in his flippers and suck his brains out. We thought that was myth, but when we looked into it, there are walruses in the northern arctic who are known to eat seals. And that's what they do, they hold them in their flippers, puncture a hole in their head and suck their brains out.'
