Before I get into the film itself, here's the little known back-story. Roark Bradford, a white Tennesseean, was mesmerized as a boy by the sermons of a black preacher named John Wesley Henning (aka "Preacher Wes). Rev. Henning entertained and educated his audiences with imaginative biblical tales done in a fashion in which his rural black audiences could relate. Years later in 1928, Henning's twists on biblical tales were the basis of Bradford's book "Ol Man Adam and His Chillun." Marc Connely enjoyed the book, and the result was the play and film "The Green Pastures." The film and play adds the charming frame device of Mr. Deeshay, a black Sunday school teacher telling the Biblical tales from Bradford's text with Noah, Adam. Moses, et.al. as Southern rural blacks. Much has been said about the dialect and stereotypes. Fact is, the dialect is pretty close to the truth of this time and place, as my parents were of that generation (there is a reference to "Sonny Kick Mammy Wine." My parents would make me laugh at their description of a popular moonshine called "Fight Your Mama" that was supposed to have been so potent that it would make the drinker do as the title suggested).
However, the film, as well as much of Bradford's work, is filled with moving truths about the human condition. Witness the dialog between a pre-Rochester Eddie Anderson as Noah and the dignified Rex Ingram as God, as well as the observations about human nature made throughout the film. As for ending, I won't spoil it, but the final scene before the credits says the true message of the film without saying a word. Watch it with an open mind, enjoy, and think.
Incidentally, in 1963, the great comedian Mantan Moreland (who had a bit part as an angel in "The Green Pastures") went back to the source and recorded an album of tales from the source "Ol Man Adam And His Chillun." It's as delightful as the film and along with the original books, make a great addendum to the film.
