Rare original vintage Australian Daybill movie poster. The Bells of St. Mary's is a 1945 American drama film produced and directed by Leo McCarey and starring Bing Crosby and Ingrid Bergman. Written by Dudley Nichols based on a story by Leo McCarey, the film is about a priest and a nun who, despite their good-natured rivalry, try to save their school from being shut down. The character of Father O'Malley had been previously portrayed by Crosby in the 1944 film Going My Way, for which Crosby had won the Academy Award for Best Actor. The Bells of St. Mary's has come to be commonly associated with the Christmas season, due most likely to the inclusion of a scene involving a Christmas pageant at the school, and the fact that the film was released in December 1945.
