The Serpent and the Rainbow

Christophe's eyes opening in the coffin is the first hint that he has been turned into a zombie, not truly dead. Captain Dargent Peytraud, a bokor (sorcerer), used the zombie drug on Christophe shortly after his initial death, leaving him in a trance-like state buried alive. The tears rolling down his cheeks suggest Christophe was conscious inside the coffin, unable to move or scream, experiencing the horror of being buried.

The opening scene foreshadows Alan's own burial later in the film, when he too experiences being buried alive while technically dead.

Captain Dargent Peytraud is the main antagonist and a bokor, a voodoo sorcerer who practices black magic. He serves as a commander in the Tonton Macoute, the brutal paramilitary force supporting Jean-Claude Duvalier's regime. Peytraud can create zombies by using a special powder to induce death-like trances, then enslaving the victims' souls. He steals souls of his enemies to gain power and uses supernatural possession to control people from afar.

Alan first sees Peytraud as the mysterious suited man at Christophe's funeral in 1978, foreshadowing his role as the mastermind behind the zombie operations.

The zombie drug is a powder containing toxins from puffer fish and other poisonous compounds that induce a death-like trance. When administered, it slows the heartbeat to nearly undetectable levels, making the person appear dead. After burial, the subject awakens in a semi-conscious state but remains enslaved to the bokor who created them. The drug also allows the sorcerer to control the victim's actions and eventually steal their soul.

Alan's vision in the Amazon shows him the suited man surrounded by corpses in a pit, foreshadowing his encounter with the zombie drug and Peytraud's soul-stealing operation.

The torture serves as both punishment and intimidation. Peytraud wants Alan to abandon his mission and leave Haiti. The specific method, a nail through the groin, mirrors the male goat sacrifice ritual used in voodoo, symbolizing castration and spiritual weakening. The Tonton Macoute also frame Alan for Christophe's sister's murder by staging the scene with her decapitated body beside him while he was unconscious.

The torture foreshadows the final confrontation, where Alan uses the same method, driving a nail into Peytraud's groin, to defeat him using white magic.

Christophe rescues Alan because, despite being turned into a zombie by Peytraud, he retains some humanity and free will. Having already been saved once by Alan (who discovered he was alive and not buried), Christophe repays that debt. Even as a zombie, Christophe helps Alan escape, suggesting the zombie drug doesn't completely erase the victim's consciousness or moral sense.

This mirrors the opening scene where Christophe's eyes opened at his own funeral, suggesting zombies retain some awareness of their fate.

Alan defeats Peytraud by drawing on white magic from the houngan Lucien Celine, who had taught him protective rituals before being killed. In the climactic battle of wills, Alan drives a nail into Peytraud's groin, the same method used to torture him, reversing the symbolic castration ritual. This act sends Peytraud's soul to hell, destroying his supernatural power and freeing the souls he had stolen.

The torture Alan endured earlier foreshadows this exact method of defeating the villain, turning Peytraud's own brutal tactics against him.

Peytraud uses soul-stealing to accumulate power and maintain control over Haiti. By turning enemies into zombies, he eliminates them physically while enslaving their souls, preventing them from opposing him in life or death. The beheading of Mozart and other sacrifices empower Peytraud's dark magic, allowing him to possess people and extend his influence beyond physical death.

The canari (pot) displaying Celine's soul demonstrates how Peytraud collects and stores stolen souls to fuel his power.

Mozart is beheaded by Peytraud as a blood sacrifice to increase his supernatural powers. Despite helping Alan obtain the zombie drug and secretly boarding the flight to America, Mozart returns to Haiti and pays the ultimate price for his involvement. His death underscores the danger of playing with dark forces and Peytraud's willingness to eliminate anyone who opposes him.

Mozart's earlier deception (selling rat poison instead of the real zombie drug) and his desire for fame set the stage for his tragic fate.

Peytraud possesses the wife to send Alan a warning and demonstrate his supernatural reach extends beyond Haiti. During a celebration dinner in America, he takes control of her body to deliver a chilling message about Alan's impending death. This possession shows that Peytraud's power isn't limited by geography and that he can strike at Alan even in the United States.

The possession foreshadows the final conflict and demonstrates Peytraud's ability to manipulate people remotely through soul magic.

The film is set during the brutal reign of Jean-Claude Duvalier (Baby Doc), whose Tonton Macoute paramilitary forces maintained power through terror and violence. Peytraud's role as a captain in this force connects supernatural evil to real political oppression. The film's ending, where the people celebrate after Peytraud's defeat, suggests the fall of the bokor parallels the eventual overthrow of the Duvalier dictatorship in 1986.

The constant political upheaval throughout the film establishes the environment where Peytraud's dark practices could flourish unchecked.

The pharmaceutical company believes the zombie drug's active compound could be developed into a powerful anesthetic, a 'super anesthetic' that could revolutionize medicine. By inducing a death-like state without causing actual death, the drug's properties could allow for painless surgeries and revolutionary medical procedures. This commercial interest drives the entire plot, funding Alan's expedition to Haiti.

The company's funding creates the conflict that draws Alan into Peytraud's territory, setting the supernatural battle in motion.

The title references the serpent as a symbol of evil and death (associated with Peytraud's black magic and the snake-like corruption in Haiti), while the rainbow represents hope and salvation. The film progresses from the serpent's dominion, torture, soul-stealing, political terror, to the rainbow's promise of liberation. The final scene, where Marielle declares 'the nightmare is over' as the people celebrate, embodies this transformation from darkness to hope.

The title's duality is established early: Peytraud's serpent-like control versus the eventual liberation of Haiti and Alan.
