The profession of capturing animals in action on celluloid is both an art and science. Some of the most exciting footage can be obtained in different ways. Examples are: a large herd, such as of reindeer, moving as one; slow motion footage of fast moving animals, such as racing greyhounds, especially when they do something unexpected; mothers and their newborn offspring doing what comes naturally; animals placed among special props; animals placed in human situations; combining the exciting and dangerous, such as the running of the bulls in Pamplona and the bullfights to follow; placing animals that are not natural companions together; and placing animals in the situation of a challenge, such as a bunch of bananas just out of reach of a hungry monkey. Many of these elements are combined into the final sequence of a steeplechase race.
