Al Pacino is a practising Roman Catholic. In many photgraphs, you can see he wears roasary beads. I have seen him many times leaving a Roman Catholic church in New York, which speaks Latin. There was an interview in which Pacino stated that the only place he was allowed to go as a child was "Church, school and the movies". In the early 1970s, after breifly lapsing in his religion, Pacino began attending church again, this was during "The Godfather" filming, so perhaps it was the culture of the Italian Americans that was making him feel closer to his religion, who knows? However, he is a practising Roman Catholic, and is quite religious.
