Major Themes – Monstrosity (1963)

Explore the central themes of Monstrosity (1963), from psychological, social, and emotional dimensions to philosophical messages. Understand what the film is really saying beneath the surface.

🧬 Identity

The story probes what makes a person when a brain is transplanted into a different body.

💰 Greed and Power
