The Dark Night (Spanish: La noche oscura) is a 1989 Spanish-French drama film directed by Carlos Saura.

It stars Juan Diego as John of the Cross in solitary confinement in a Carmelite monastery in Toledo in 1577.

They force him to stand trial, but John refuses to obey the friars, unwilling to ask for forgiveness for his Reformist beliefs.

The image of Justina, the nun, appears but this time, she wears a dark blue dress.

John narrates the story of a woman in the convent who people came to listen to because she seemed dictated by the Devil.

In the present, John announces that he is too proud, interrupting a dinner and the head priest's Bible reading.

In June, John hears Justine's voice saying he needs to leave the monetary because he has other, more important work to do in the outside world.

At the beginning of the film, a priest in the monastery reads historical facts about John's life when he enters the hall for the first time for his trial.

Teresa is represented in a negative manner because the priest says that she has created a conspiracy, therefore presenting the tensions between the different Carmelite groups from the beginning.

John's escape from the window using the rope made of his robe is also in line with the historical facts that we have.

According to El País, the film explores the central question surrounding John's famous life: “¿Cómo, en efecto, en tan atroz adversidad se las arregló Juan de la Cruz para componer tal exquisitez, una tan delicada música de la palabra?

[2]” (translation: “How, indeed, in such atrocity and adversity did John of the Cross resolve to write words so exquisite, delicate, and musical?”).

The manner in which the filming techniques present Juan Diego in such intense moments helps us to understand how the poet was able to write something so important to Spanish literature in such terrible conditions.
