The thin line between order and anarchy is the theme of Howard Hawks’s greatest comedies, and it finds its perfect expression in this 1952 story of a chemistry professor (Cary Grant) who unknowingly discovers a youth serum. He and his wife (Ginger Rogers) psychologically revert to teenagers, then children, as all their unspoken impulses come bubbling up under the influence of the drug. Very funny and strangely frightening—Hawks’s comedies are invariably more pessimistic than his dramas—Monkey Business ranks with the best works of the American cinema.
