BBC The Natural World. In 2004, a team from the Planet Earth series captured the first ever film of a wild snow leopard in the mountains of Pakistan. For Nisar Malik, who led the expedition, these images sparked a passion that compelled him to return. With cameraman Mark Smith, he spent two years documenting the snow leopard's daily life, finally lifting the veil on the most elusive of all cats.
