"Wild Indonesia" presented a particular logistical challenge for us. How to cover 17,000 islands spread across an area stretching from New York to London. Once we'd figured that out, we were then faced with how to access the animals there, many of which were rarely seen, let alone researched. As we had tied ourselves to telling the story of Indonesia's evolution, we had to make sure we did every island and every species' story justice. Obviously, we couldn't cover everyone, but we certainly had a go. The series has one of the highest species counts of any I have ever worked on.
