Belgian actor Jérémie Renier released a feature documentary titled “D’un monde à l’autre” in cinemas on June 10, 2026 [2].

The film serves as a public meditation on grief and friendship. By documenting a grueling physical journey, Renier explores the psychological trauma following the loss of his best friend, French actor Gaspard Ulliel.

Renier undertook an expedition to the Arctic, known as the Grand Nord, alongside explorer Loury Lag [1]. The journey was designed as a way to process the death of Ulliel, who died four years ago in 2022 [1]. Renier said the expedition was a response to a period of stagnation in his life, stating, "Je n’arrivais plus à avancer."

The documentary captures the intersection of physical endurance and emotional recovery. Renier said the motivation for the trip was tied to a shared existential struggle, noting that "la peur de la mort entourait nos motivations."

Throughout the filming process, Renier maintained a spiritual connection to the late actor. He said, "Gaspard Ulliel, mon ami, m’a accompagné en pensée durant tout ce voyage." The film has begun screening at venues including the Quai 10 cinema in Charleroi [1].

The project marks a transition for Renier from the immediate shock of loss to a structured form of remembrance. The expedition allowed him to transform a private tragedy into a cinematic exploration of the human spirit's ability to persevere through mourning.

“Je n’arrivais plus à avancer”

The release of “D’un monde à l’autre” illustrates a growing trend of artists using immersive, physical challenges to document the grieving process. By linking the desolate landscape of the Arctic to the internal isolation of loss, Renier provides a visual metaphor for the 'impossible' nature of mourning a peer, shifting the narrative from the suddenness of Ulliel's death to the long-term labor of recovery.
