The Keys of the Kingdom is a 1944 American film, which was nominated for Academy Awards in the following categories: Best Actor in a Leading Role (Gregory Peck), Best Art Direction-Interior Decoration, Black-and-White, Best Cinematography, Black-and-White and Best Music, Scoring of a Dramatic or Comedy Picture.

The film was adapted from a 1941 novel by A. J. Cronin. Spanning four decades, it tells the story of an unconventional Scottish priest who struggles to establish a Catholic mission in China.

Alfred Hitchcock, a Catholic, liked the novel very much and hoped to direct it, but the plans fell through. Also, Ingrid Bergman was considered for the part of Mother Maria-Veronica, though the producer, Joseph L. Mankiewicz, decided to cast his wife, Rose Stradner, instead.

A young priest, Father Chisholm (Gregory Peck) is sent to China to establish a Catholic parish among the non-Christian Chinese. While his boyhood friend (Vincent Price), also a priest, flourishes in his calling as a priest in a more Christian area of the world, Father Chisholm struggles. He encounters hostility, isolation, disease, poverty and a variety of set backs which humble him, but make him more determined than ever to succeed. Over the span of many years he gains acceptance and a growing congregation among the Chinese, through his quiet determination, understanding and patience. Written by E.W. DesMarais
