Factual error: In the beginning of the movie, we saw the Ring of the Fisherman of the dead pope, inscribed with his name: "PIUS XVI". However, the inscription should be done in Latin style, which uses "V" instead of "U". Thus the correct inscription should read "PIVS XVI". The Latin style of writing is evident in the Ring of the Fisherman that is worn by the real, currently reigning pope, Benedict XVI, which is inscribed "BENEDICTVS XVI".

Continuity mistake: When the antimatter explodes in the helicopter, the the shock-wave blasts off part of the roof inside St. Peter's Basilica, above the alter, obliterating everything below. However, in the scene where the Camerlengo self immolates himself at the altar close to the end of the movie, there is no evidence of the shock wave earlier, the candles are burning, oil lamps are lit and alter is intact.

Visible crew/equipment: In their first visit to the Vatican Archives, Robert and Vittoria are sitting at the table across from one another. When Vittoria asks Robert "Do you need help with Latin?" the shadow of the boom mic is seen moving on Robert's face. (00:37:45)
