Conclave

Factual error: The Torre delle Milizie is visible from the courtyard in the Vatican and looks fairly close. You can't even see the tower from the Vatican. It's quite a long way away.

Character mistake: The official in charge of announcing the voting results keeps pronouncing Cardinal Adeyemi's name in different ways; he puts the accent on the last "e" the first time, then the French way on the last "i", then mere seconds later the "e" again. Considering Adeyemi already walked in the conclave as one of the 4 favourites, and that utmost care was put in the preparation of the ceremonial (in an earlier scene, Ralph Fiennes' character makes sure he knows how to pronounce the name of one of the unimportant cardinals), it's quite the egregious mistake that he keeps repeating.
