This journal, written during the filming of Of Gods and Men by Xavier Beauvois – dedicated to the assassination of the monks of the Tibhirine monastery in Algeria – offers a rare insight into the acting profession.

Jean-Marie Frin, who plays Brother Paul in the film, honestly shares his constant doubts. He describes a continuous self-questioning, not hesitating to profoundly examine his Christian upbringing, while keeping his mind alert, driven by a quest for truth in order to best meet the director's expectations.

This testimony, both unique and deeply sincere, allows us to grasp the unique atmosphere of an extraordinary filming, marked as much by the power of its subject as by the quality of those who participated in it.

The book is enriched, in its center, by a section featuring 140 photographs taken on set.
