Book excerpt: When cameras roll and directors call, “Action,” some of the most dependable, funniest, and most enthusiastic actors stand poised on four legs, with ears alert. From Joey in War Horse to the wolves in Game of Thrones, what we see on screen is the result of meticulous preparation and professional teamwork. The eye-popping, heartwarming stories in these pages reveal the trainers, actors, directors, and, of course, dogs, cats, horses, penguins, deer, and other animals in all their behind-the-scenes glory. You’ll discover that some animal actors have diva tendencies and others have rags-to-riches backstories. American Humane Association certified animal safety representatives work carefully to ensure that no animals are harmed, as they have been doing for decades. Animal stars have done it all — convinced us to eat more tacos, broken our hearts in war dramas, inspired us with enduring love and loyalty, kept us at the edge of our seats as they snarled in the shadows, mirrored human antics to make us roar with laughter, and, like Uggie (from The Artist), stolen the show on the red carpet. Who besides a monkey named Crystal could impress a brilliant comedian like Robin Williams in Night at the Museum? And animal stars will work for food, including only KFC original recipe for Casey the bear — no other fried chicken will do! These charming and sometimes hilarious stories will give you a new appreciation for the skill and patience it takes to teach nonhuman actors to perform on camera. Training tips from the pros and personal recollections of celebrities such as Julia Roberts, Hailee Steinfeld, and Steven Spielberg make this insider’s look at the lives and work of these incomparable stars as irresistible as the animals themselves.
