Akihiro Hata’s Debut: Exploring Human Behavior in Film

A construction site, workers and mysterious disappearances. These are the ingredients of “Grand Ciel”, a fiction which reminds us that we should never trust appearances.

No electricity, but workers required to continue their work on the Grand Ciel construction site, “a new kind of neighborhood, economically responsible” described as a first in France. The tone is set from the start of Japanese filmmaker Akihiro Hata‘s first feature film, in theaters Wednesday January 21. The pressure is permanent in this fiction and it is multifaceted: economic, social and romantic.

Vincent, played by Damien Bonnard, is a temporary worker on the Grand Ciel construction site. He goes out with Nour, played by Mouna Soualem, who has a little boy. He looks forward to living with her and his son. To do this, he hopes to continue working on the site where one of his teammates has just disappeared. A few days later, another disturbing disappearance occurs. Saïd, alias Samir Guesmi, intends to shed light on these incidents. Vincent, who nevertheless shares his concerns, prefers to play the card of caution.

By reconstructing his life as a couple, his personal aspirations and his professional development on this site, Akihiro Hata introduces us to Vincent, but above all sheds light on his motivations: cowardice or simply the desire to keep his job to afford the family life he so aspires to and improve his social condition?

In a setting where daily life, clear and bright, contrasts with a nocturnal construction site life, dark, dusty and sometimes evanescent, we discover Vincent and his comrades prey to a disturbing work environment.

As the plot unfolds, its issues appear completely different from what one might imagine. And if there is an investigation, it is not necessarily the one we think of. Big Sky is a film that is worth it, at the risk of becoming boring, because it requires patience, particularly attention to small, innocuous sentences, and invites subtlety to penetrate Vincent’s behavioral mechanics. The man is confusing, difficult a priori to be understood, especially since Damien Bonnard composes an affable character. His reactions seem more and more surprising given the disappearance of his colleagues and the tensions they cause in his workplace.

The feature film thus revisits, with a certain skill, the psychological thriller against a backdrop of social aspiration. Watching Akihiro Hata’s first feature film is like launching into a labyrinth without really realizing it. Worth a try, if only to assess your talents as a (fine) psychologist.
