British husband-and-wife production team, noted for their influential animated (animation) films.

Halas was educated in Hungary and Paris and apprenticed to George Pal; he moved to England as an animator in 1936. After art school Batchelor became a commercial artist and met Halas in 1936 while working on Music Man (1938). They later married and in 1940 established Halas and Batchelor Animation, Ltd., which became the largest cartoon film studio in Great Britain.

The collaborators directed and coproduced their greatest work in 1955, an animated version of the George Orwell (Orwell, George) novel Animal Farm, England's first full-length colour feature cartoon. Their other projects included The History of the Cinema (1956); Automania 2000 (1963); Dilemma (1982), the first fully digitized film; and more than 2,000 other animated films. Many later cartoons, documentaries, and educational shorts were commissioned specifically for television. Halas was made an officer of the Order of the British Empire in 1972.
