One of the most influential and unsettling films of the 1950s, Don Siegel’s sci-fi/horror classic charts the escalating panic that grips a California town as residents find their friends and loved ones being replaced by emotionless alien “pod people.” Interpreted as an allegory for everything from the McCarthyist fear of Communist infiltration to the stifling conformity of the Eisenhower era, INVASION OF THE BODY SNATCHERS transcends its drive-in B-movie origins to become a still-terrifying vision of a society’s descent into mass hysteria.
