Curiosidades

About this film, Ingrid Bergman said "It wasn't a very good picture. But as long as a part makes sense, and the character is a human being, I will try because I can't do artificial people on the screen. Nothing done with such a character can make it real to audiences." With Ratoff's permission, Bergman introduced changes to her character that turned Emilie from a cardboard saint to a humanized woman, such as adding the scenes in which she did gymnastics and played basketball with the boys. Bergman would humanize her Sister Benedict in The Bells of St. Mary's (1945) with some similar athletic character development.

Ingrid Bergman, making only her second American film, was borrowed from David O. Selznick Productions to appear in the film. Director Gregory Ratoff also directed Bergman's first American film, a Selznick picture entitled Intermezzo (1939). Writing about Adam Had Four Sons in her autobiography, Bergman said, "At last something my teeth could bite into, but it was not such a good apple. We had a script to work with but the dialogue was made up minute by minute as we went along, and they had no idea how to end the picture. Ruth Roberts [her dialogue coach] was an enormous help, and great affection for the crazy Gregory Ratoff, so it all left a very pleasant souvenir."

This picture marked former radio announcer Robert Sherwood's (not to be confused with Robert Sherwood the playwright) debut as a film producer.

Only film featuring both Ingrid Bergman and Susan Hayward, future Academy Award winners.
