A place with so many sharks it was dubbed "Shark Island" by the few who have been there. The film looks at how underwater volcanoes sustain a food chain that ends with hundreds of feeding sharks. Working with stunning imagery is always a joy, but it was especially exciting to be working with the BBC Natural History Unit for the first time. This led onto other sound tracks with the BBC NHU including a recently completed 26-part series due to be broadcast in 2010.
