This richly illustrated work is a history, critical analysis, and celebration of the Halas and Batchelor Cartoon Studio, Britain's leading and most influential animation company from 1940 to 1995. This lavish study draws on the archives of the Halas & Batchelor Collection and looks at the studio's key works, including Animal Farm, Britain's first full-length animated film; The Tales of Hoffnung, with the legendary Peter Sellers; and the cult classics Butterfly Ball, featuring the work of Beatles illustrator Alan Aldridge, and Autobahn, with the music of Kraftwerk. The book includes an autobiographical account by Vivian Halas, daughter of the company's founders, as well as critical insights by animation professor Paul Wells. Animation worldwide is indebted to John Halas and Joy Batchelor for their outstanding work. This book explores their legacy.
