There’s an italian saying about the Pope succession system that doesn’t really translate well into english, but it’s basically a clerical version of “the king is dead, long live the king”, and with this thriller (based on a Richard Harris book of the same name) we see indeed the titular conclave, held in order to vote the next Pope, with the cardinals being ritually closed off from the world until from the Sistine Chapel a white puff of smoke can be seen, signifing a new Pope has been chosen.

The conclave is held by a recalcitrant Cardinal Lawrence (Ralph Fiennes), that eventually gets a hold of many secrets about the many other Cardinals moving their influence around to get elected as the “Sacred Big Cheese”, from affairs to hidden documents, rampant display of a hunger for power, realpolitik stuff and an even darker secret that could shake the very core of the Church itself..

And yes, it’s nowhere near as profound or complicated as the movie treats itself, with most of the Cardinals vying for power being nearly cartoonishy douches, the speeches making thing way too simple, and the final reveal being honestly kinda ridiculous (and really selling the “whodunnit” – minus the murder – structure of the film), but direction by Edward Berger (All Quiet On The Western Front) really sells the isolated world where these holy men are forced to live until the deed is done, that even if you can guess most of the resolution, it’s equally enthralling to see it unfold, and the acting from the cast (full of great character actors) is often amazing, sometimes hammy but still immensely entertaining, that it elevates what would be otherwise quite silly stuff in context.

Even with these flaws, it’s undeniably a worthwhile watch for the acting alone.
