Major Themes – Murder by Natural Causes (1979)

Explore the central themes of Murder by Natural Causes (1979), from psychological, social, and emotional dimensions to philosophical messages. Understand what the film is really saying beneath the surface.

🃏 Deception

Deception drives every interaction, with Arthur presenting himself as a trusted mind-reader while manipulating lovers and rivals. Allison and Gil exploit the moment of fear to advance their plan, unaware of Arthur's broader game. The film uses the loaded gun and staged danger to illustrate how a lie can control events and people. The reveal shows how long lies can shape fate before the truth dismantles them.

🎭 Power Play

Power and social status dictate motives and outcomes as wealth buys silence. Arthur's psychological manipulation functions as a weapon, forcing others to act against their will. Alliances form and fracture within the mansion's walls and during the garden party. The climactic betrayal reveals who truly commands the household.

🗡️ Revenge

Revenge drives the characters beyond jealousy into calculated retaliation. Arthur's counter-move flips the script, using others' plans to justify his own vengeance. The finale recontextualizes earlier actions as premeditated retaliation rather than self-defense. The ending leaves the moral balance unsettled, suggesting vengeance perpetuates harm.
