This silent movie from 1927 was produced and directed by Ernest Schoedsack and Merian C Cooper, who went on to create King Kong.

Chang shows the film-makers getting closer to the world of King Kong. A family in the northern forests of Siam battle snakes, leopards, tigers and a vast herd of elephants.

This is pre-conservationist, pre-PC cinema. Forget about "no animals were harmed in the making of this picture". No animals were un-harmed is more like it. This is about real jungle beasts getting really shot.

Watching it is the nearest thing a 21st-century audience will get to an old-fashioned tiger hunt. It's almost like a National Geographic snuff movie. The whiff of danger is real.
