What 1945 film stars Bing Crosby and Ingrid Bergman as a priest and a nun?

The 1945 film starring Bing Crosby and Ingrid Bergman as a priest and a nun is The Bells of St. Mary's.

Leo McCarey produced and directed this comedy-drama, written by Dudley Nichols from McCarey's story. Crosby plays Father Chuck O'Malley, while Bergman plays Sister Mary Benedict. Their good-natured disagreements center on preserving a struggling parochial school threatened with closure.

The film follows Going My Way (1944), in which Crosby first played Father O'Malley. That earlier film won him the Academy Award for Best Actor, making the sequel especially easy to confuse with its predecessor. The Bells of St. Mary's was also a major success and received eight Oscar nominations, including Best Picture and acting nominations for both stars.

It won the Academy Award for Best Sound Recording. Its title also echoes a popular 1917 song, though the movie's story is set around the fictional St. Mary's school and church.
