Who played Monsignor Hugh O'Flaherty in the movie "The Scarlet and the Black"?

In the 1983 movie, Gregory Peck played the Irish Monsignor Hugh O'Flaherty, a Vatican official. O'Flaherty set up a rescue network for escaped Allied POW's in the face of Vatican concerns for the safety and neutrality of the church and active Gestapo assassination attempts. He and his network saved over 6,500 escapees and Jews.

Gregory Peck (April 5, 1916 – June 12, 2003) was an American actor who was one of the most popular film stars from the 1940s to the 1960s. Peck continued to play major film roles until the late 1980s. His performance as Atticus Finch in the 1962 film "To Kill a Mockingbird" earned him the Academy Award for Best Actor.

The movie was based on the book "The Scarlet Pimpernel of the Vatican" by J. P. Gallagher published in 1967. The scarlet and the black in the movie title refers to the black cassocks and scarlet sashes worn by monsignores, as well as the colors of the Nazi Party regalia.

After the war was over, O'Flaherty made monthly visits to the imprisoned SS chief, Colonel Kappler played by Christopher Plummer, who had ordered his assassination. O'Flaherty was instrumental in saving the family of his enemy after the liberation of Rome. In 1959 the Monsignor baptised the Nazi into the Roman Catholic Faith.

Monsignor O'Flaherty was decorated for his war work by several of the Allied countries, including the United States.
