Film-makers describe shooting Under The Sea
Epic filming in the Coral Triangle
But for the film-making duo's latest memorable film foray in the underwater world, such obstacles are just part of the process of bringing some of the Earth's most amazing marine sights to audiences around the world.
With 2 expeditions to Papua New Guinea, and 6 weeks in southern Indonesia around Komodo Island, the film crew got their fill of marine biodiversity.
Says Michelle: "You often see garden eels standing about 75 cm on the bottom when diving in tropical waters but what was remarkable about these was their size. They were gigantic, standing at more than 2 m high."
Not always a pretty sight
According to Howard, one of the most beautiful sites the team visited was a reef in Komodo Island. As he recalls, "our guide said it breaks his heart to dive there. He said that at one time you'd see 7 species of sharks in a single dive at that location. These days you don't see any."
At a place called Calypso Reef in Papua New Guinea, they saw spectacular corals and complete coral cover where a few years ago the reef had been completely bleached during the 1998 El Niño event.
Where WWF comes in
"WWF also helped us to understand how important it was to single out the Coral Triangle as a region, so that people can begin to learn about it" says Michelle.
