Alec Guinness was spotted in costume when walking home through the French countryside. A young boy ran up to him, yelling "Mon père! Mon père!" ("My father! My father!") Guinness did not speak French, so he could not correct the young boy's mistake, but was touched that the young boy apparently immediately bonded to him on the assumption that he was a priest. Soon after the film was released, Guinness converted to Catholicism.
