One day in 2011, Barns received a phone call from film director Andrew Graham-Brown, asking if Barns would be interested in doing a ‘taster tape’ about his life with kangaroos. The ‘taster tape’ is kind of like a move trailer made to entice broadcasters to commission a film or show. The tape Andrew and Chris made was well received by the BBC and they decided to fund a two-part series for Natural World.
