Why is a dog man's best friend? How do you get a pig to sing? This Omnibus special takes an entertaining and anecdotal look at animals in film and traces how human attitudes to our fellow creatures have changed over the century. With help from those who train animals to perform in front of the camera and using film and television clips, the programme explores the art behind stars such as Lassie, Babe, Flipper, Mr Ed the talking horse, Elsa, Beethoven and Willy.
