The Liminal Space

The cinematic waiting room where characters lose their pasts and await their futures.

In cinema, the liminal space is a physical transition zone that mirrors a character's internal state of suspension. Rather than mere backdrops, these thresholds—be they highways, rooftops, or half-built rooms—force characters to confront who they were before they can decide who they will become. By trapping protagonists between two worlds, filmmakers turn geography into psychology.

Cinema loves a threshold, a place where the rules of the ordinary world are temporarily suspended. In Rain Man (1988), this transition is literalized through the cross-country road trip in the 1949 Buick Roadmaster. Trapped between the rigid structure of an institution and the chaotic allure of the real world, the highway becomes a neutral zone where two estranged brothers can finally learn to communicate without the baggage of their pasts. Other times, the liminal space is defined by height and exposure. The iconic rooftop meetings in Infernal Affairs (2002) elevate characters above the gritty reality of Hong Kong's streets. Suspended between the sky and the pavement, these rooftops are the only places where an undercover cop and a mafia mole can shed their double identities, existing in a dangerous, high-altitude purgatory where truth and deception blur. If rooftops offer a temporary escape, the unfinished new apartment in The Salesman (2016) represents a domestic limbo. With its exposed wires and unpainted walls, the half-completed flat mirrors the crumbling marriage of its protagonists. It is a space of raw vulnerability, too raw to inhabit but impossible to ignore, symbolizing a transition that has stalled midway. In Three Colors: Blue (1993), the liminality is fluid and immersive. The recurring swimming pool scenes serve as a sensory womb where Julie retreats to escape her grief. Submerged in the blue water, she is suspended between life and death, memory and oblivion, using the pool as a quiet, isolated holding pen for her trauma. Finally, Closer (2004) weaponizes the concept through the recurring motif of glass surfaces (aquarium, windows, lenses). These transparent barriers keep characters perpetually on the outside looking in. The glass acts as a cold, liminal boundary—close enough to tease intimacy, but solid enough to prevent actual connection, keeping these lovers forever suspended in a state of emotional near-miss.

Examples

• Infernal Affairs (2002) — The recurring motif of the rooftop meeting space.
  The recurring motif of the rooftop meeting space serves as a crucial liminal space within the film. These rooftops are more than mere settings; they function as a symbolic third space, a threshold suspended between the legitimate world of police headquarters and the illicit underworld. They represent a precarious, temporary zone of moral ambiguity where the characters' true, conflicted identities are momentarily revealed, highlighting their precarious existence.
• Three Colors: Blue (1993) — The recurring swimming pool scenes
  The recurring swimming pool scenes serve as a liminal space, a symbolic, transitional zone between Julie's traumatic past and an uncertain future. The water's blue enclosure offers a womb-like state of suspension, a place of both sensory deprivation and intense feeling. Here, Julie can retreat from the world and undergo a process of quiet, internal transformation and rebirth, making the pool central to her emotional journey.
• The Salesman (2016) — The mise-en-scène of the unfinished new apartment
  The mise-en-scène of the unfinished new apartment functions as a liminal space. Its state of incompletion—with unpainted walls, exposed wires, and boxes—physically represents the transitional and unstable state of Emad and Rana's relationship after the trauma. It is a space that is neither the old home nor a new beginning, trapping them in a psychological "in-between" where old rules no longer apply and a new normality cannot yet be established.
• Rain Man (1988) — The cross-country road trip in the 1949 Buick Roadmaster
  The cross-country road trip in the 1949 Buick Roadmaster functions as a liminal space. Occurring between institutional confinement and commercial exploitation, this transitional journey suspends normal social rules. This liminality allows for Charlie’s profound moral and emotional transformation, revealing the drive as a modern-day purgatorial quest for redemption. The journey itself becomes the crucible for his personal growth and ethical awakening.
• Closer (2004) — The recurring motif of glass surfaces (aquarium, windows, lenses)
  The recurring motif of glass surfaces, such as aquariums, windows, and lenses, functions as a symbolic threshold. These glass surfaces are not just part of the setting but represent the characters' state of being in-between intimacy and alienation. They can see each other but cannot truly connect. The glass separates and distorts, perfectly visualizing the flawed, mediated nature of their relationships and the barriers to genuine human connection.
