I was sold on seeing “Conclave” just by the sheer force of its cast. Ralph Fiennes, Stanley Tucci, John Lithgow, and Isabella Rossellini instantly put the film on my radar. But for me the biggest draw was Edward Berger, the director, co-writer, and producer of the 2022 Academy Award-winning masterpiece “All Quiet on the Western Front”. Whatever the acclaimed filmmaker delivered as his next feature would be an instant must-see.

“Conclave” is an absorbing thriller that’s fueled by powerhouse performances and driven by a filmmaker who maintains an assured grip until he loses it in the final ten minutes. The film is a mostly captivating experience, frustrated only by a curveball ending so out of left field that it derails the near perfection that came before it. It’s a wild final swing that is little more than an eleventh-hour plot device, desperately aiming to be provocative, but too underdeveloped to be anything other than outrageous.

“Conclave” is based on the 2016 international best-selling novel of the same name by Robert Harris. For the majority of its time, screenwriter Peter Straughan’s adaptation plays like a high-stakes political thriller. It’s cloaked in mystery with several big reveals, some unexpected twists, and a lingering sense of paranoia. You can’t help but be sucked in by this ecclesiastical potboiler set within the hallowed halls of the Vatican.

The movie opens with Cardinal Thomas Lawrence (Ralph Fiennes) arriving at the Vatican after getting word the pope has suddenly died. After carrying out the ceremonial rites, the throne is officially declared vacant. From there, Father Lawrence is tasked with overseeing the papal conclave – a gathering in Rome of Cardinals from around the world for the purpose of electing a new pope.

From the first moment we meet him it’s obvious that Cardinal Lawrence isn’t thrilled with his responsibility. We learn he has recently struggled with a crisis of faith leading to his desire to resign from his position and leave Rome. At the same time, he also proves himself to be the most qualified and capable person to handle such a significant task. Fiennes commands the screen yet works with a necessary restraint. His weary eyes and burdened gaze gives us a good look into his tired and troubled soul.

Soon after the cardinals are sequestered and the process begins, four frontrunners arise. There’s Cardinal Bellini (Stanley Tucci), a staunch liberal pretending to be uninterested but with a clear desire for the papacy; Cardinal Tedesco (Sergio Castellitto), a conservative caricature with hardline views that some feel would set the church back decades; Cardinal Adeyemi (Lucian Msamati), a Nigerian archbishop who quickly emerges as the favorite; and Cardinal Tremblay (John Lithgow), a politically savvy American bishop whose every action is driven by his ambition to be the next pontiff.

After none receive the required two-thirds majority, a second vote is held followed by a third and a fourth. Tensions rise as the candidates posture for position, use internal politics to their advantage, and in some cases resort to underhanded tactics to compromise their competition. Caught in the middle is Cardinal Lawrence who must navigate the accusations and potential scandals to ensure the integrity of the process. And what’s with the arrival of Cardinal Benitez (Carlos Diehz), the archbishop of Kabul who was secretly appointed by the late pontiff?

Berger goes to great lengths to make his film look as authentic as possible, recreating with painstaking detail everything from the Vatican’s ornate interiors to the vibrant priestly regalia. Meanwhile Stéphane Fontaine’s cinematography and Volker Bertelmann’s score add think layers of tension as the story progresses. And it all builds our anticipation for what should be a rich and juicy finish. But instead “Conclave” ends with a whimper, throwing in a last-second twist that’s given no buildup and has no notable narrative or dramatic connection to anything that preceded it.

For 110 minutes “Conclave” is hands-down one of the year’s best movies. Unfortunately its final 10 minutes turns it into one of the year’s most frustrating misfires. The ensemble is top-notch, the production design is stellar, the behind the scenes wrangling is riveting, and Berger’s direction is methodical and propulsive. It makes the film’s unraveling all the more discouraging. Rather than ending with a bang, “Conclave” is given a lazy, patronizing finish built more on sanctimonious intentions than good moviemaking judgements.

VERDICT – 3.5 STARS
