It’s that sound. Those few plucking notes of a banjo that immediately make your skin crawl, even if you’ve never actually seen the movie. James Dickey’s 1970 novel and the subsequent 1972 film directed by John Boorman didn't just create a cinematic masterpiece; they birthed a cultural shorthand for rural terror. But for decades, people have been obsessed with a single question: what is the deliverance based on and did those horrifying events actually happen to someone on a river in Georgia?
The short answer? It’s complicated. It isn't a "true story" in the way a true crime documentary is, but it’s far from pure fiction. It’s a messy, violent cocktail of James Dickey’s real-life ego, a very specific era of American anxiety, and a harrowing canoe trip that almost claimed the author’s life.
The Real Canoe Trip That Started It All
James Dickey wasn’t just a writer; he was a guy who desperately wanted to be seen as a "man’s man." He hunted with a bow, he drank hard, and he loved the idea of being an outdoorsman. In the early 1960s, long before the book hit the shelves, Dickey went on a canoeing trip down the Coosawattee River in Georgia. He wasn't alone. He was with two friends, Lewis King and Al Braselton.
This is where the foundation of the story lies.
They weren't expert woodsmen. They were city guys—advertising executives and academics—trying to conquer a river that didn't care about their resumes. During the trip, they got into serious trouble. The water was higher than they expected. The rocks were sharper. At one point, Dickey actually flipped his canoe and found himself trapped in the churning water, staring death in the face.
He survived, obviously. But the psychological trauma of being helpless in the wilderness stayed with him. He started wondering: what if the river wasn't the only thing trying to kill us? What if the real danger was the people who lived there?
When people ask what is the deliverance based on, they are often looking for a specific police report about a sexual assault in the woods. There isn't one. The "squeal like a pig" scene, which has become the most infamous moment in movie history, was a product of Dickey’s imagination—sorta. He took the very real vulnerability he felt on that river and dialed it up to a nightmare level. He wanted to explore the "atavistic" nature of man. Basically, he wanted to see what happens when a "civilized" person is stripped of their laws and forced to become a predator to survive.
The Chattooga vs. The Coosawattee
If you go looking for the river from the movie today, you’ll find the Chattooga River. It straddles the border of Georgia and South Carolina. It's beautiful. It's also dangerous. But the book was actually inspired by the Coosawattee.
The tragedy is that the Coosawattee River as Dickey knew it no longer exists.

The "deliverance" in the title refers, in part, to the "delivering" of the river from its natural state. Shortly after Dickey's trip, the Carters Dam project began. The valley was flooded. The rapids were buried under millions of gallons of water. The wild, untamed wilderness was "tamed" by the Army Corps of Engineers. This sense of a disappearing world is the backbone of the narrative. Ed, Lewis, Bobby, and Drew are there to see the river one last time before it's gone.
Why the Chattooga became the face of the film
When John Boorman showed up to film the movie, he couldn't use the Coosawattee because it was already being dammed. He moved the production to the Chattooga. This created a weird, meta-reality. The locals in Rabun County, Georgia, were hired as extras. The "Banjo Boy," Billy Redden, was a local kid who didn't even know how to play the banjo (someone else's arms were reaching around him to do the fingering).
The tension you see on screen between the "city boys" and the "mountain men" wasn't entirely acting. There was a genuine culture clash happening. The locals felt—rightly so—that they were being portrayed as monsters. Dickey, who was on set and famously difficult, kept insisting that the mountain people he encountered on his real trips were "remnants of an older, stranger world."
The Lewis Medlock Inspiration
While the plot is a dramatization, the characters are heavily based on Dickey's real social circle. The character of Lewis Medlock—played by Burt Reynolds in the film—is essentially a heightened version of Dickey himself, or at least the man Dickey wanted to be.
Lewis King, the man who accompanied Dickey on the original trip, was the primary blueprint. King was a survivalist type, someone who believed that civilization was a thin veneer that would eventually crack. Dickey took King’s philosophy and turned it into the driving force of the story.
Interestingly, Burt Reynolds and James Dickey did not get along. At one point, Dickey showed up on set drunk and started a fight with the director. Boorman actually kicked him off the set because Dickey’s "expert" posturing was becoming a liability. It's a classic case of an author being so tied to the "real" inspiration of his work that he couldn't handle the Hollywood version.
Is the Assault Scene Based on a Real Event?
This is the darkest part of the "what is the deliverance based on" rabbit hole. For years, rumors circulated that Dickey had heard a story about a surveyor or a woodsman being assaulted in the Georgia mountains.
There is no documented evidence that this specific crime occurred to Dickey or his friends.
However, Dickey was a student of the "Southern Gothic" tradition. He was obsessed with the idea of the "frontier" and the violence inherent in American history. He used the assault as a narrative device to completely break the characters. In the 1960s and 70s, the idea of male-on-male sexual violence was a taboo that carried a specific kind of "urban" horror. By placing it in the middle of the "pure" wilderness, Dickey was flipping the script on the classic American camping trip.
It wasn't based on a fact; it was based on a fear.
The fear was that the "civilized" man is actually weak. When Bobby Trippe is assaulted, the group's hierarchy collapses. Lewis, the "hero," can't protect them from the human element, only the river. It’s a brutal commentary on the inadequacy of modern masculinity when faced with raw, lawless aggression.
The Legacy of the "Real" Deliverance
The impact of the story was so massive that it actually changed the geography of the South. After the movie came out, tourism to the Chattooga River skyrocketed. People wanted to "ride the Deliverance river."
The irony is staggering.
A story about the dangers of the wilderness and the destruction of nature by outsiders led to a massive influx of outsiders who often died because they weren't prepared. In the years following the film's release, the death toll on the Chattooga rose significantly. People were showing up in Kmart life jackets with no experience, trying to find the "thrill" they saw on screen.
The "real" Deliverance is the story of how we view the rural South. To this day, the "Deliverance" trope is used to dehumanize Appalachian and rural Southern communities. It created a lasting stigma that the people of Rabun County have had to fight for fifty years.
Actionable Insights: Understanding the Context
If you want to truly understand what this story is built on, you have to look past the shock value.
- Read the book first. The movie is great, but Dickey’s prose explains the internal "why" much better than the film. The book is more about the internal decay of the men than the external threat of the hillbillies.
- Research the Carters Dam. Understanding the environmental destruction of the Coosawattee gives the story its "ticking clock" feel. The river was literally being murdered by progress.
- Look into the "New South" movement. Deliverance was written during a time when the South was rapidly industrializing. The conflict in the story is a literal representation of the old, wild South being forcibly integrated into the modern world.
- Respect the river. If you visit the Chattooga, remember that the "Deliverance" story is fiction, but the river’s power is 100% real. It’s a Class IV/V river in sections. Don't be a statistic.
The reality is that what is the deliverance based on isn't a single event. It’s a collection of James Dickey’s memories, his deep-seated insecurities about his own toughness, and a genuine mourning for a landscape that was being paved over in the name of electricity and "civilization." It’s a ghost story about a river that isn't there anymore and a type of man that probably never existed in the first place.
When you strip away the banjo music and the Hollywood gloss, you're left with a very human truth: we are often most afraid of the things we don't understand, whether that's a Class V rapid or the person living just around the bend in the river. Dickey just had the guts (and the ego) to put that fear on paper.
To dive deeper into this, look up the "Coosawattee River" archives or read "Way Down Yonder on the Chattahoochee" by Harry Norman. These sources provide the most grounded, non-sensationalized accounts of the real-life inspirations that Dickey twisted into a nightmare. Understanding the environmental history of Georgia's rivers provides more "truth" than any urban legend about the film's production.
