‘All You Need to Make a Movie Is a Gun’ Review: Found Footage and the Politics of Memory
An Argentine filmmaker uncovers lost student films from the 1960s–70s, reconstructing lives shaped by political upheaval, repression, and cinema’s enduring power as memory and resistance. Shown at the Rotterdam, BAFICI and FICIC film festivals.
History is built in layers. Cinema is too. Images, in particular, are among the most decisive of those layers: what gets filmed, preserved, or remembered eventually hardens into “fact,” especially when no other records exist. How many of our memories survive only because a photograph or a piece of footage keeps them alive? How much would we have forgotten if it hadn’t been fixed in time by a home movie or even a single image?
Over the course of a gripping two and a half hours, Córdoba-born filmmaker Santiago Sein undertakes an act of excavation in All You Need to Make a Movie Is a Gun. The film brings back to the present memories thought lost, stories that were never fully told, while also functioning as a deeply cinephile tribute to a group of people who believed cinema could help transform society—many of whom paid for that belief with their lives.
The story begins—within a narrative that constantly blurs the line between fact and fiction—with the discovery of several deteriorating film reels, presumed lost, at the School of Arts of the National University of Córdoba. Shot between 1956 and 1976, most of them unlabeled, they contain short films and assorted footage made by students during those decades. Structured in three parts, Sein gradually reveals these materials: some fictional, others documentary, many of them increasingly politicized in the wake of the Cordobazo—a major workers’ and students’ uprising in 1969 that marked a turning point in Argentina’s political radicalization.
The first chapter, The Weapons, focuses on exploring the contents of these reels: protests, marches, staged scenes, and fragments of political life. Through conversations with surviving participants, a story begins to take shape—that of a group of young film students and activists (Rodolfo “Rudy” Wratny, Oscar Moreschi, Roberto Videla, Ernesto Ascheri, Cristina Sorini, Alberto Perona, as well as French Pierre Vigier and Gerard Guillemot, among others) who made films together, debated them, and argued about cinema’s role in a rapidly shifting world.
Sein not only shows the archival footage but foregrounds the physical processes that make it visible: opening film canisters, cleaning fragile strips, threading projectors. The emphasis on these tactile gestures turns the act of viewing into something akin to a forensic excavation—carefully uncovering a body to understand what it contains and what stories it can still tell. In that sense, the film also becomes a documentary about its own making: how to approach this material, what kind of film can emerge from it, and how these fragments can function as a kind of reenactment of their own production.
The second part, Spring in Autumn, shifts toward a more poetic and speculative register. Here, Sein introduces a newly recorded voiceover that reconstructs the possible lives of those involved, drawing from both the documentary and fictional footage—most of which lacks original sound. The narration plays like a diary from the period, likely informed by testimonies and anecdotes shared with the director. Through this interplay between image and voice, the film builds a hypothetical narrative of these students: their friendships, ideals, and creative ambitions.
As Sein has noted, this is “a narrative decision and an exercise in imagination.” What follows moves fluidly between the poetic and the political, documentary and invention. It becomes a reconstruction tinted with fiction, tracing the trajectory of these young filmmakers through the 1970s: their enthusiasm, militancy, struggles, persecutions, and eventual fragmentation. And at the center of it all, cinema itself—filming obsessively, urgently, as a way of bearing witness to a chaotic era.
The third chapter, Scorched Earth, adopts a more conventional documentary form, but its emotional impact is devastating. Through present-day testimonies, it recounts what became of most of the people involved: stories of internal betrayals, arrests, forced disappearances, and ongoing searches for the missing. These events are inseparable from Argentina’s last military dictatorship (1976–1983), a period marked by state terrorism and the disappearance of thousands.
In one of the film’s most powerful gestures, Sein uses the same Bolex camera employed in the original student films to document a recent march on March 24—the annual Day of Remembrance for Truth and Justice in Argentina, which commemorates the victims of the dictatorship. In that demonstration, people still demand answers about the disappeared film students from Córdoba—the same young faces we’ve seen onscreen, smiling, hopeful, unaware of what lay ahead. Past and present converge through cinema, that enduring device of collective memory.
Somewhat bafflingly relegated to a side section of the BAFICI titled “Films About Film,” All You Need to Make a Movie Is a Gun feels destined to become a key work for understanding the relationship between Argentine cinema and the political history of the 1970s. Not just because of what it tells, but because of how it tells it: by working with images captured in their own time—rather than relying solely on retrospective interviews—while creatively recontextualizing them and foregrounding the cinematic apparatus as an essential part of its meaning.
This is an important, revelatory film—one that, in 2026, pushes against the prevailing cultural climate. A work of cinephile, political, and anthropological excavation, it investigates, imagines, questions, pays tribute, and mourns. Above all, it recalls—with both pain and nostalgia—a group of film students who tried to document the turbulent world they inhabited, but did not live long enough to tell their stories.
These are, or might have been, those stories.
