Built for the Kill is a nature series made by Granada Wild for the National Geographic Channel. It was made from 2001–2004, with a total of 31 episodes. Each episode runs for approximately 48 minutes including the credits and opening titles. Episodes of Built For The Kill cover a topic or habitat for predatory animals, such as "Coral Reef" or "Packs". If the episode is the name of a Habitat, the episode will feature predators from that environment. If the episode's name is something like "Jaws" or "Packs", it will feature predators who utilize the name of the episode. Built For The Kill uses a graphical approach to catch the audiences attention, often showing inner workings of the predatory animals by using diagrams. Some effects seen are used to show the audience what they can't really see, but is there. This graphical approach to a nature documentary makes Built for the Kill very interesting to watch. Built for the Kill's classic opening was a montage of creatures featured in the first 7 episodes with a catchy theme song. This opening was changed further into the series to one that shows the National Geographic logo in various parts. The theme song stayed the same however.
