Edward Berger’s Conclave is not really about Catholicism. It’s about institutions — what they conceal, what they protect, and what happens when the machinery of legitimacy meets a secret it cannot process. That it’s set inside the Vatican is almost incidental. The College of Cardinals could be a corporate board, a politburo, a supreme court. The dynamic is identical. Ralph Fiennes plays Cardinal Lawrence, tasked with managing a papal election after the sudden death of the Pope.
