In Hollywood Hoofbeats, author Petrine Day Mitchum tells stories in page-turning detail, covering topics such as behind-the-scenes portraits of both famous movie horses and those virtually unknown; personal accounts from their trainers, owners, and costars; simple and complex horse stunts, from a fall in mid-gallop to a race across a bridge during a live explosion; and historic black-and-white photos and richly colored contemporary stills.
