The Way Back
This is a film that probably can be used in the form of film clips but would not justify viewing the entire film for the purposes of understanding Stalin and his particular form of evil. But it is a great film for understanding that the weakness of kindness can actually be a strength that restores humanity to a person.
Derived from the name of a Greek pagan goddess of peace, Irena does bring peace but also an opportunity for the characters to grow more human. Irena tells a tale of being a farm girl who witnesses the murder of her parents at the hands of the Soviets and is then sent for work on a collectivized farm. She escapes. Mr. Smith puts her story to the test by Irena's improbable geography. The truth is, her parents were Polish communists who emigrated to Russia during the salad days of the post-Revolution period but are later arrested by Stalin's regime. Irena is placed in an orphanage.
Irena serves as a bridge between the men, allowing their own crimes and evil to rise to the surface. The admission of the past is not something that destroys them but serves as an opportunity for grace and forgiveness. She exhibits the feminine genius of at once disarming and empowering men to be more themselves.
For how she does it one must watch the film.
