here is the official Italian trailer of Luca Barbareschi’s film based on the work by David Mamet

For several years now, at the theatre, Luca Barbareschi is working on the lyrics of David Mametunanimously recognized as one of the greatest living playwrights (he is the one, to understand, of the screenplay of The postman always rings twice And The verdictbut above all of the theatrical work “Glengarry Glen Ross”which later became the film Americans).
And exactly Mamet is the text underlying the new film produced, directed and starring the volcanic Barbarywhich is called The Penintent and which, after being presented at the Venice Film Festival last September, will arrive in theaters from May 30th with 01 Distribution.
This the official plot of the film:

New York. A psychiatrist finds his career and personal life derailed after refusing to testify on behalf of a violent and unstable former patient who caused the deaths of several people. The young patient’s belonging to the LGBT community, the doctor’s Jewish beliefs, the press’s hunger for news and the severe judgment of the law, aggravated by a printing error by a newspaper editor, seem to be the elements that trigger a explosive chain reaction.
The media pillory and the ferocity of the judicial system add to the moral dilemma of the professional who hides behind the Hippocratic oath to defend himself from the questions, pressures and betrayals of everyone in search of the truth. So who is the monster? The boy? The doctor? The print? Justice? Who can say they are innocent?

In addition to Barbareschi in the title role, the cast of The Penitentshot between Rome and New York, are also there Catherine McCormack, Adam James and Adrian Lester.
Thus Barbareschi spoke about the story written by Mamet, which he himself adapted for the big screen, and the conflicts and themes it addresses:

I loved the theatrical version of this text as much as I love the film version which follows the thriller pattern. The screenplay written by a genius like David Mamet is inspired by a news case, the Tarasoff case. The protagonist of our story is a psychoanalyst whose life was destroyed – as was the case with many university professors, teachers and managers – due to the fury of two other protagonists, who are, in the film and in life, the invasive judicial system and the piloted communication.
When a man’s private life clashes with the mechanism of a communication that is not elaborate dissemination of news, but which is instead defamation, that is, visual and intuitive provocation, determined to make judgments rather than to inform, a conflict arises. And if a judicial system that identifies a victim outside of the real victims and a culprit in someone who is not the real culprit also participates in the conflict, then we are in the midst of a tragedy. But why does this happen? Mamet says: “Because human nature is cruel.”
