Robert Harris, a renowned historical novelist, captivated readers with his latest thriller, Conclave. The novel offered a fictionalized account of a papal conclave, providing a fascinating glimpse into the complex dynamics and power struggles that could occur within the Vatican. At the heart of the Conclave was the election of a new pope, a momentous occasion that drew the attention of the global Catholic community. However, the process itself was far from straightforward. A group of cardinals, known as the College of Cardinals, gathered in the Sistine Chapel to elect a new leader of the Church. The conclave was a highly secretive affair, with participants isolated from the outside world and subject to strict rules of conduct.

Conclave delves into the intricate and secretive process of electing a new pope following the death of a pontiff. The narrative unfolds within the Vatican's hallowed walls, where Cardinal Lawrence is thrust into a web of political intrigue and moral dilemmas as he oversees the papal conclave. The film captures the tension and drama of this ancient ritual, exploring themes of power, faith, and human frailty. The story begins with the sudden death of a pope, which sets off a series of ballots among the cardinals. As Cardinal Lawrence navigates the complexities of the election, he discovers hidden scandals and conspiracies that threaten to destabilize not only the conclave but also the very foundations of the Catholic Church. The stakes are high, with each vote carrying profound implications for millions of followers worldwide.

Edward Berger's directing is renowned for its dramatic tension and careful attention to detail. Although Peter Straughan's screenplay extensively uses Harris's novel, it also ensures that viewers who are not familiar with the original work can still enjoy the movie. Straughan highlighted the significance of authenticity in depicting the customs and rituals of the Vatican, which required in-depth study and even a private trip to Vatican buildings to fully convey the spirit of this hallowed establishment. The claustrophobic visual aesthetic of Conclave, which reflects the cramped quarters of the Vatican, heightens the sense of urgency and secrecy throughout the movie. Both the majesty of religious buildings and the characters' hardships are depicted in the cinematography. This mood is complemented by the score, which heightens the emotional impact of each scene.

In addition to examining the internal conflict within the Church between tradition and growth, the movie dives into the workings of papal elections. While Tucci's character adds a layer of interest with his strategic maneuvering, Fiennes's portrayal of Cardinal Lawrence is praised for its intricacy. According to early reviews, Conclave is a gripping novel that makes readers consider their identity, faith, and authority within the Catholic Church. The film asks viewers to consider the difficulties of leadership during turbulent times by fusing character development with suspense.
