When the first pope is chosen a black smoke canister is used, yet white smoke appears.
2005 Bergoglio (thicker hair, older glasses) is seen in the airport heading to Rome in 2012 after his resignation note summons.
The movie implies that Jorge Bergoglio cooperated with the Argentinian junta and therefore was exiled once the rule of the military was over. This is not true. Bergoglio stopped being the provincial superior of the Society of Jesus in Argentina in 1979 (not 1983 as shown in the movie) because his terms were over at this time. After that he wasn't banished but served as the rector of the Philosophical and Theological Faculty of San Miguel in San Miguel until 1986. It is also not true that Bergoglio became fond of liberation theology at this time. The opposite is true - Bergoglio refused to teach his disciples liberation theology and chose a direct pastoral approach instead. This was the reason for his dismissal in 1986.
In the confession scene Benedict XVI starts talking about Fr. Marcial Maciel and implies that he covered his crimes. The opposite is true. Before becoming pope Cardinal Jospeh Ratzinger started two investigations against Maciel (in 1999 and 2005) and after becoming pope Benedict XVI removed Maciel from office in 2006. Shortly after that, Maciel died.
The movie implies that Bergoglio cooperated with the Argentinian junta and betrayed his fellow Jesuits and Argentinians. The opposite is true. The two shown Jesuits priests Jálics and Yorio are real people. They survived the junta thanks to Bergoglio who relentlessly begged the authorities for their release from prison. There also countless other witnesses who survived the junta in Argentina because of Bergoglio. Many of them thank Bergoglio in the book "Francis. The real story of his life" written by Agnieszka Gracz and Adam Sosnowski.
The movie depicts Jorge Bergoglio having a fiancée and almost getting married to a woman named Amalia. Those events are fictionalized. Her character is based on Amalia Damonte, who grew up in Bergoglio's neighborhood, and often attended school with him. In the book "Pope Francis: The People's Pope", Damonte explains that their "romance" is based on a love letter that Bergoglio wrote to her when he was 12 years old, saying, "If I can't marry you, I'll become a priest." In the book, Damonte said: "The media made me the pope's fiancée, which is not true. We were 12 years old at this time and good friends, that's all."
When Cardinal Bergoglio quotes the Bible to Pope Benedict he says it is from Isaiah 41 Chapter 10. It should be Chapter 41 Verse 10.
In one scene, after a long discussion, Pope Benedict gives Pope Frances a CD of Abbey Road. The background music then chimes the music and lyrics of "Blackbird," which is from the album the Beatles released before Abbey Road, The Beatles ("White Album")
Both Pope Benedict and Pope Franciscus are completely fluent in Italian. So their short dialog that "speaking English is exhausting - so many exceptions to every rule" would definitely not have happened in reality.
Jorge Bergoglio rhetorically asks Pope Benedict why the leaders of the US, Russia and China seek his advice. No Pope has ever met a leader from the People's Republic of China.
