Thunderball was a... a new experience for all of us, because we had to work underwater, and so the whole art department was learning to swim with bottles, and so on. But we also used the Ivan Tors' people, who were working in Miami, doing a... a Flipper series, which was very popular, and they were underwater experts, but we had several near disasters. The... the first one was that I had, from the air, found this incredible villa with two pools, a seawater pool and a freshwater pool. And I rang up the sea aquarium in Miami and said if we could get some actual sharks to drop into the seawater pool, and in one night they fished about 15 sharks, and they were, you know, some 10ft, and big bloody sharks, you know dropped into the pool. Then I remembered that the owners of the villa, and I shalln't mention their name, were fond of having maybe too many drinks at night time, so I had to provide a guard overnight in case somebody would drop into the shark pool, which was pretty awful because the smell already was... was terrible. But, you know, those Ivan Tors' people used to swim them around the pool to keep them alive, and we had to put... feed oxygen, and so on.
