After completing a PhD on gelada baboons in Ethiopia, Chadden worked with National Geographic, PBS and Discovery Channel, filming everything from tribal ceremonies in Africa to snow leopards in Pakistan. On the BBC series Planet Earth he became known as ‘the guy covered in bat poop’, and whilst filming arctic wolves for Frozen Planet learnt that minus 40C was cold enough to freeze his eyes shut. His television series, including Wild Arabia, Planet Earth 2 and most recently Seven Worlds—One Planet have won multiple Emmy and Bafta awards. After 20 years of filmmaking with Sir David Attenborough Chadden has now returned home to help grow the natural history film industry in Australia.
