If the sound effects seem overamped, George Fenton's score is always on the money, adding humor and suspense at crucial moments (martial drums for the mud skippers, woozy brass for the Darwin's beetle). Nonetheless, delicate sensibilities may find some sequences disturbing, as when Komodo dragons feed on a water buffalo or when a leopard seal dines on a penguin (according to Attenborough, the Komodo siege caused the camera operators "emotional turmoil"). More often, the filmmakers capture the moment of impact before moving on. The set comes complete with 10 featurettes on the four-year production.
