Andana Films Takes Sales on Detention

Andana Films has stepped in to handle worldwide sales for “Detention,” giving Guillaume Massart’s new documentary a sharper international path just before its Cannes debut.

The film will premiere in the ACID sidebar at the Cannes Film Festival later this month, a slot that often spotlights singular independent work outside the main competition glare. Reports indicate “Detention” marks Massart’s second feature and turns its camera toward France’s prison officer academy, where trainees undergo a process of professional and psychological formation.

“Detention” enters Cannes with a clear premise and a timely setting: the making of prison officers, observed from the inside.

The project appears to build its tension through observation rather than overt argument. According to the summary, the documentary watches as the recruits’ language, gestures and certainties slowly begin to align, suggesting a close study of how institutions shape identity from the ground up. That framing could give the film weight far beyond its immediate setting, especially as public debate around authority, discipline and incarceration continues across Europe.

For Andana Films, the acquisition adds a Cannes title with a strong festival identity and a subject that can travel through documentary and arthouse circuits. For Massart, the ACID launch offers a high-visibility platform for a film that seems less interested in spectacle than in the slow construction of power, obedience and belief.

What happens next will likely depend on how “Detention” lands with Cannes audiences and buyers looking for nonfiction work with a strong point of view. If the film connects, it could push a tightly focused institutional portrait into a wider conversation about the systems that train, direct and transform the people who enforce the state’s authority.
