Don Siegal’s Invasion of the Body Snatchers is impressive because of its potent bleakness, which slowly engulfs the film like a distant shadow that grows in size. The stark black and white look complements this all-encompassing feeling along with the frantic close-ups in the third act. At its heart though is a terrifying idea that another version of ourselves can replace us with no sense of the human experience. Our memories have no meaning to this replacement other than being an unnecessary byproduct. Thus, the central question of the film becomes whether or not our emotions are a necessary part of life? By the film’s admission, the answer seems to be a resounding yes.
