From the Safety Valve to the Question of What Is True
There is a historical theory, formulated by Frederick Jackson Turner, that argues something quite simple and powerful at the same time: the frontier—the West not yet organized, not yet tamed by civilization—served as a safety valve for much of American history. When established society became too rigid, too crowded, or too demanding for those who didn't fit in, there was a concrete way out: leaving. The misfits, the discontented, those who couldn't tolerate hierarchies, those who needed a fresh start, had a physical place to go to. Turner wasn't exactly saying that the frontier was the natural destination for crazy people—that's a freer, more narrative reading of his idea—but he did hold something close to it: that the westward expansion operated as a relief mechanism, a way of decompressing the tensions that civilization kept accumulating.
What is interesting is not so much the thesis itself—which can be read in any American history textbook—but what happens when someone takes it out of its academic context and uses it to ask a much more uncomfortable question: what happens when there is no frontier left? That is precisely what Interstate 60: Episodes of the Road (2002) does in the scene where Bob Cody explains Turner's theory to Neal Oliver, as their car passes a sign that reads "Frontier." Cody tells the story with irony: those who didn't fit in the East packed their bags and headed West, and the punchline—predictable yet effective—is that a good portion of those misfits ended up in California.
That's where the first plot twist appears, and it's the one I find most interesting: California is not merely the end point of that exodus of the discontented. It is also the largest entertainment factory in the country and one of the wealthiest states in the entire United States. The frontier that once served as an escape from society ended up turning into one of the most intense expressions of that very same society. You don't have to stretch the interpretation to see the irony: the place you went to leave civilization behind ended up being the place where civilization learned to mass-produce its own dreams. This isn't something Turner predicted—attributing that intention to him would be absurd—but it is precisely the kind of twist a film can afford: taking a serious historical thesis and using it as a springboard for a philosophical question.
False Frontiers
Cody doesn't stop at geography. He says something that completely shifts the register of the conversation: Turner died in 1932, before the world ran out of frontiers to offer. And then he lists the substitutes that civilization kept inventing to continue promising an escape route when the actual way out—the territory—no longer existed. Alcohol and drugs, as a chemical frontier: altering consciousness to believe you've gone somewhere else without ever leaving the spot. Computers, as a virtual frontier: the illusion of having escaped without having escaped. Space, as the "final frontier," which Neal suggests almost by reflex and Cody dismisses because it isn't a realistic possibility for almost anyone. And finally the mind, which is the only frontier that remains, in some sense, genuinely unexplored territory.
Cody's conclusion—"the frontier is right here"—is the hinge of the entire film. It turns a theory about a country's territorial expansion into a much more personal and uncomfortable question: what does a person do when they don't fit into the world they were born into, but have nowhere left to go?
Advertising as a Fake Frontier
That is where the film takes the decisive step, and where the truly interesting part begins for me. Cody doesn't stop at an abstract meditation on psychological frontiers: he starts listening to radio commercials and breaking them down, ad by ad. A car marketed as American even though the engine is Japanese. A movie that "everyone is talking about," when in reality no one is talking about it. A service that claims to care about people. Every time, Cody's reaction is the same: "that's a lie." Not because all advertising is necessarily false in an absolute sense, but because he is attuned to the gap between what is claimed and what is actually delivered.
And then he drops the detail that retroactively reorganizes the entire scene: he used to work in advertising himself, he was paid to lie, and one of those lies contributed to a boy's death. As if that weren't enough, his own lung cancer is, in his words, a death sentence by nicotine. The very industry he helped build ended up collecting its tab. The equation the film sets up is almost brutal in its economy: advertising → lie → real harm → death → decision to spend the rest of his life dismantling lies.
Here we can see why advertising can be read as a false frontier, in exact parallel to Turner's geographical frontier. The historical frontier said: if you don't like this society, leave. Modern advertising says something else, cheaper and more effective: if you don't like your life, buy another one. You don't need to move anywhere. It's enough to buy the car, smoke the cigarette, watch the movie "everyone is watching," to feel that you have accessed, for a moment, a different life. Drugs and computers operate on the same logic: they offer the sensation of escape without the cost—nor the risk, nor the work—of actually escaping.
What separates Cody from a simple cynic laughing at commercials is precisely the dead boy. That's where the film stops treating the subject as a series of jokes about marketing and starts treating it for what it truly is: a matter of consequences. It's not enough to distrust an advertising claim. You have to ask what happens when someone believes it. Who benefits if I believe this? What are they hiding from me by telling it to me this way? Who pays the price if the claim turns out to be false? Cody is not just a skeptic of words; he is a skeptic of consequences, which is a much more demanding and uncomfortable position to hold.
The Museum That Displays Fraud as Fraud
The movie applies this exact logic to an even more literal setting in the scene at The Museum of Art Fraud, located in the fictional city of Renburg, presented as "the greatest art museum in the world, disguised as a cheap roadside attraction." The curator tells Neal that her husband, a collector and technical expert, had developed a method to duplicate paintings at an almost molecular level. He would borrow a masterpiece from a major museum, craft a perfect copy, return the copy, and keep the original. The result is a total inversion: the prestigious New York museum unknowingly displays a fake, while the ridiculous, decaying museum in a lost town houses the originals. According to the curator, even The Starry Night in New York and the Monet believed to be in Paris are copies.
However, the most interesting part isn't the joke about the ownership of the works, but the experiment the scene conducts on the viewer. Visitors first walk through the room of originals—without knowing they are originals—and criticize them: "it's a copy," they say, pointing out flaws and commenting on how inferior the technique is compared to the "real" painting. Then they move into the room of copies—believing them to be the originals—and praise them. The same work, the exact same potential physical object, changes in value depending on the label attached to it. It isn't the object that dictates the judgment: it's the narrative accompanying it.
There, the museum becomes a sort of staging area for everything Cody has been pointing out since the car ride. What makes something original? The object itself? The signature? The provenance? The authority of the museum displaying it? What the catalog says? What the expert claims? Or simply what we believe we are seeing at the moment we look at it? The scene doesn't stop at discussing art fraud: it turns the viewer—the film's audience, and in a way, us as well—into the victim of a real-time epistemological fraud. We know the museum visitors are wrong. But during those minutes, we too passively accept the narrative the film feeds us.
The Fälschermuseum and the Preservation of Deception
There is, in reality and not in fiction, a museum remarkably similar in spirit: the Museum of Art Fakes in Vienna (Fälschermuseum), operating since 2005 and dedicated exclusively to art forgeries and frauds, featuring works by notorious counterfeiters like Han van Meegeren, Tom Keating, Eric Hebborn, Elmyr de Hory, or Konrad Kujau. The film doesn't mention it—it's a real museum, not a script reference—but examining it alongside the fictional Museum of Art Fraud helps complete the argument.
What makes the Fälschermuseum special is that it does not destroy a fake once it is uncovered: it preserves and displays it as precisely what it is. A painting that once succeeded in fooling someone now says, "look at how they were fooled." The fraud ceases to be merely a completed trick and becomes an object of study into the mechanics of deception. It is no longer enough to know that something is fake: we need to understand how it managed, for a time, to appear real. And in many of these cases, what is forged isn't just the physical object—the painting, the signature—but its history: where it came from, who owned it before, how it was discovered. Object plus history produces the feeling of authenticity. It is the exact same formula, barely disguised, that advertising uses: product plus narrative produces desire. "This car is American." "This cigarette makes you free." "This movie is the one everyone is watching." The object may be completely real and functional. The fraud lies in the story wrapped around it.
Closing the Loop: From Turner to Epistemology
When laid out end to end, the trajectory becomes clear. Turner describes a territorial frontier: when society squeezes too hard, there is a physical place you can escape to. Cody notes that this frontier has disappeared and that civilization, to avoid leaving anyone without a safety valve, invented substitutes: drugs, screens, space as an unattainable fantasy, the mind as the last genuine territory. Advertising offers an even more efficient variation: you don't even need to escape your own life, it's enough to buy the symbol of another. Art forgery takes the same logic to the extreme of the object: you don't need to produce the original, it's enough to produce something similar enough for the story of authenticity to hold up. And the museum—both the fictional one and the real one in Vienna—takes that exposed forgery and turns it into a tool for studying deception itself, rather than simply discarding it.
There is a progression here worth naming: frontier, escape, representation, deception, detection, skepticism. And at some point along that path, the frontier stops being a place and becomes a distance: the distance between what a thing is said to be and what it actually is. Turner's question—"Where does civilization end?"—first transforms into "Where can I escape from it?", and finally ends up, guided by Cody, as something much closer to Montaigne or Taleb than to the history of American territorial expansion: "What part of what I am seeing is real?"
That final question is, at its core, the only frontier still standing when there is no new territory left to move to. It is neither geographical, chemical, nor virtual: it is the uncomfortable, unprofitable, and almost always counter-cultural habit of refusing to accept a claim simply because it arrives backed by authority, prestige, a well-written catalog, or a convincing story—and choosing instead to ask where the deception might be hidden, and what happens to someone if they end up believing it.
