Yes, this is based on a stage play! Yes, Clark Gable already had his famous moustache then! Yes, Joan Crawford is wearing a new dress each time she enters the screen, No, it's not a movie directed by an auteur! Yes, Joseph L. Mankiewicz wrote the screenplay of Forsaking All Others! Yes, it's a pre-code film with a lot of sex scenes (if you don't believe me, see it)! Recommended.
