This is a review of the movie The Brothers Karamazov (1969) based on the novel by F. Dostoevsky (original title Bratya Karamazovy).
Most of the discussions taking place throughout the film are highly spiritual and contain such topics as faith in God, the existence of the soul, bad and good acts, etc.
The movie Legends of Autumn (1994) by director Edward Zwick is worth a look.
My favorite hero here is Colonel William Ludlow. The father of three sons, he lives in the middle of nature, away from urban civilization.
The Altered States (1980), director Ken Russell,is a thought-provoking spiritual movie.
A key phrase is a double choice for Darkness.
