The French documentary Detention (original title: La Détention) has been picked up for worldwide sales by Andana Films ahead of its debut in the ACID sidebar at the Cannes Film Festival. Directed by Guillaume Massart, the film represents his second feature-length work and follows a cohort of recruits inside a national academy where future prison officers are trained. Produced by Céline Loiseau for TS Productions, the project offers an observational look at how individuals are shaped by an institutional environment.
Inside the film: training, language and institutional shaping
Detention positions its camera within the routines and exercises of an academy for prison staff, documenting how speech, posture and certainties evolve as recruits adapt. Rather than showing the prison interior, Massart focuses on the educational setting to map the processes that produce those who will staff carceral institutions. The film deliberately keeps the cells and inmates off-screen, using the training ground as a lens to examine the broader social machinery behind incarceration. This approach frames a discussion about the relationship between state institutions and individual transformation.
Festival strategy and distribution
By entrusting worldwide sales to Andana Films, the film’s producers aim to give Detention an international commercial and festival circuit. Andana’s involvement comes at a key moment as the film prepares for its world premiere in the ACID sidebar, a section known for promoting independent and auteur-driven works. The selection places Massart’s film in a context that prioritizes distribution opportunities for filmmakers who take unconventional or socially engaged approaches to documentary storytelling.
Comments from the creative team and sales partner
Producer Céline Loiseau described the ACID selection as an ideal platform for the film, stressing that Massart’s observational method provides immersion into the technicalities of training while keeping the physical prison out of frame. ACID was invoked as an arena where independent projects can be highlighted for theatrical distribution and critical attention. Meanwhile, Stephan Riguet of Andana Films noted that the company has followed Massart’s career closely and sees the ACID outing as recognition of his longitudinal creative effort.
Critical framing from ACID
Members of the ACID committee — Maxime Jean-Baptiste, Thomas Paulot and Paola Termine — placed the film within a tradition of cinema that interrogates institutions by zooming in on their personnel. They argued that by centering on prison guards in training, the film creates a contained institutional micro-universe where bureaucratic procedures and ideological frameworks are revealed. The committee highlighted how Massart captures both speech and silence from the academy’s agents, documenting a discourse that appears to be fraying at its edges.
What the ACID selection signals
The inclusion in the ACID sidebar signals support from a filmmaker-led association committed to helping independent films reach theatrical audiences. ACID (a collective that champions distributor relationships and visibility for indie cinema) has maintained a Cannes sidebar since 1992, offering a platform distinct from the festival’s main competition. This year’s edition runs May 13–22, placing Detention into a program designed to attract cinephiles, critics and buyers focused on non-mainstream cinema.
Positioned between the production team and international buyers, the film now moves into a phase where festival exposure and sales representation will shape its post-Cannes path. With its observational focus on the making of prison officers rather than on incarceration’s consequences, Massart’s second feature seeks to stimulate conversations about how institutions reproduce themselves and how culture and training intersect within carceral systems. As the film prepares for its ACID world premiere, stakeholders are watching to see how this intimate portrait will travel on the festival circuit and into theaters under Andana Films’ sales strategy.
