The film is set in the 1950s, during the Atomic Age. The story centers on plutonium experiments conducted by the military, reflecting the era's anxieties about radiation, government secrecy, and the consequences of scientific hubris. This specific time period shapes the film's tone and thematic concerns about the dangers of unchecked scientific advancement.

The film explores three interconnected themes. First, Giant Growth examines physical vulnerability and the loss of humanity when power outgrows reason, serving as a metaphor for atomic-age science run amok. Second, Secrecy & Control addresses military cover-ups and how power structures obscure dangerous truths from the public. Third, Mortality probes the fragility of life as the protagonist's heart and sanity deteriorate alongside his body.

The Giant Growth theme represents the physical vulnerability and limits of humanity when power outgrows reason. Glenn's uncontrolled enlargement serves as a metaphor for the fears surrounding atomic-age science, specifically the terror of scientific discoveries that exceed human understanding or control. His transformation mirrors the anxieties of a postwar era confronting the destructive potential of nuclear technology.

Military secrecy surrounding Glenn's condition isolates him from his loved ones and the public. Officials prioritize containment over transparency, keeping the truth hidden even as the situation becomes dangerous. This theme reflects 1950s concerns about government secrecy and the tension between public safety and the public's right to know about emerging threats.
