Overview
The Left Hand of God is a 1955 American drama film. It was directed by Edward Dmytryk and produced by Buddy Adler, from a screenplay by Alfred Hayes, based on the novel The Left Hand of God, by William Edmund Barrett.
Set in a small American mission in China in 1947, at a time of civil war, it stars Humphrey Bogart as a hunted man masquerading as a Catholic priest and Gene Tierney in the role of a nurse, with a supporting cast including Lee J. Cobb, Agnes Moorehead, E. G. Marshall, and Carl Benton Reid.
While playing Anne Scott, Tierney became ill. Bogart had a personal experience as he was close to a sister who suffered from mental illness, and, during the production, he fed Tierney her lines and encouraged her to seek help.
