The Patterson-Gimlin Film
Two men captured 59 seconds of film footage showing a large, hairy bipedal creature walking through a forest clearing - the most famous and controversial evidence of Bigfoot's existence.
On October 20, 1967, Roger Patterson and Bob Gimlin were riding horses in the forests of Northern California when they encountered something that would change cryptozoology forever. Patterson captured 59.5 seconds of 16mm film footage showing a large, hair-covered bipedal creature walking through a clearing at Bluff Creek. The figure turned to look at the camera, revealing apparent breasts, then continued into the forest. The Patterson-Gimlin film remains the most analyzed and debated piece of Bigfoot evidence ever recorded.
The Filmmakers
Roger Patterson
Background: He was a former rodeo rider, a Bigfoot enthusiast, and had written a book about the creature in 1966. He was actively searching for evidence, and rented a camera before the expedition.
Bob Gimlin
Background: Bob Gimlin was Patterson’s friend, an experienced outdoorsman, and more skeptical about Bigfoot. He came along as backup and would carry a rifle for protection.
Their Purpose
They were in the area specifically looking for Bigfoot, having heard of recent sightings and brought camera equipment, prepared to document anything.
The Encounter
October 20, 1967
Around 1:15 PM, Patterson and Gimlin were riding on horseback along Bluff Creek in Del Norte County. They rounded a bend in the creek and their horses reared in alarm. They saw a creature across the creek.
What Happened
The sequence unfolded as Patterson’s horse threw him; he grabbed the camera, ran toward the creature, filming as it walked away at an angle, turned to look back at frame 352, and then disappeared into the trees.
Gimlin’s Role
Meanwhile, Gimlin controlled the horses and considered shooting the creature, deciding against it, perhaps believing it to be a human in a suit, and watched from a distance, later confirming Patterson’s account.
The Film
Technical Details
The footage was shot on 16mm Kodak film, approximately 59.5 seconds long with 954 frames, in color and at either 16 or 24 fps (debated).
What It Shows
The film captures a tall, hair-covered bipedal figure walking through a clearing near a fallen log, exhibiting apparent arm swing and stride, and the famous “look back” at the camera.
The Creature
Visible features of the creature included a height estimated 6’6” to 7’4”, dark reddish-brown hair, apparent breasts suggesting a female, a heavy build, long arms, a distinctive walking gait, and visible muscular movements.
Frame 352
The most famous image, depicting the creature turning its head and looking directly at the camera with a partially visible brow ridge and flat nose, has become iconic.
The Aftermath
Patterson’s Actions
After filming, they tracked the creature’s footprints, made plaster casts (14½ inch prints), left the area, developed the film, and began showing it publicly.
Public Response
The film caused a sensation, was shown on television, analyzed by scientists, drew skeptics and believers, and became the most famous Bigfoot evidence.
Patterson’s Death
Roger Patterson died of cancer in 1972, maintaining the film was genuine and never admitting to a hoax. The controversy outlived him.
Gimlin’s Position
Bob Gimlin has consistently maintained the film is real, passed polygraph tests, says he saw a real creature, and still speaks about the encounter, now in his 90s.
Analysis
Scientific Examination
The film has been studied by anthropologists, biomechanics experts, film analysts, special effects professionals, and computer specialists.
Pro-Authenticity Arguments
Muscle Movement: Visible muscle flexing under the hair, difficult to fake in 1967, suggests real anatomy. The Walk: A compliant gait (bent-knee walking) different from human walking, would be hard to fake. Proportions: Arm-to-leg ratios unusual for humans, consistent with reported Bigfoot descriptions, hard to replicate in a costume. Technical Limitations: 1967 costume technology was limited, a suit this good would be remarkable, Hollywood couldn’t do better.
Anti-Authenticity Arguments
The Convenient Timing: Patterson was looking for Bigfoot, he had a camera ready, he needed money, motivation for hoax. Alleged Confessions: Various people have claimed involvement, Bob Heironimus claims he wore the suit, Philip Morris claims he sold the suit, none proven definitively. Film Speed Controversy: If shot at 24 fps, the walk is more human-like; the debate about frame rate continues, affecting analysis of gait. It’s Just a Person in a Suit: Simple explanation, don’t need exotic creature, Occam’s razor applies.
The Confessions
Bob Heironimus
Years later, he claimed he wore a gorilla suit, said Patterson never paid him, his story has inconsistencies, size doesn’t quite match the figure, Gimlin denies his involvement.
Philip Morris
A costume maker, he claims he sold Patterson a gorilla suit, but timing and details are disputed, no documentation exists, his account has changed.
The Problem
None of the confessions have been proven, are fully consistent, explain all features of the film, and have been accepted as definitive.
Modern Analysis
Computer Enhancement
Digital technology has allowed frame-by-frame analysis, movement pattern study, stabilization of footage, enhanced detail viewing, and ongoing debate.
The Documentary Evidence
Recent documentaries have interviewed new witnesses, examined the original footage, applied new techniques, and reached different conclusions.
No Resolution
After 50+ years, the film hasn’t been definitively proven or disproven; experts remain divided, the debate continues, and it may never be settled.
Cultural Impact
The Image
Frame 352 is one of the most recognized images in cryptozoology, appearing in countless media and defining what “Bigfoot” looks like, shaping public imagination.
Influence
The Patterson-Gimlin film sparked serious Bigfoot research, created a template for evidence, remains the standard, and is referenced constantly.
Ongoing Relevance
Even today, new analysis is published, documentaries are made, arguments continue, and the film remains central to Bigfoot studies.
The Question
On a autumn afternoon in 1967, Roger Patterson’s camera captured something in the forests of Northern California.
Was it a real creature - an unknown primate, a relict hominid, what we call Bigfoot?
Or was it a man in a suit - an elaborate hoax by men who needed money and attention?
Fifty-plus years of analysis haven’t answered the question.
The creature’s muscles seem to move under the hair. Its proportions don’t quite match a human. Its walk is strange.
But Patterson was looking for exactly this. He had motive. People have confessed - sort of, inconsistently, without proof.
Bob Gimlin still swears it was real. He’s in his 90s now, still telling the same story.
The film remains.
59 seconds of footage.
A figure walking through a clearing.
Turning to look.
Walking into the trees.
Into history.
Into mystery.
The Patterson-Gimlin Film. The most important - and most controversial - evidence of Bigfoot ever captured.
Real creature or clever costume?
After all these years, we still don’t know.
We may never know.
But we keep watching.
Frame by frame.
Searching for the truth in those 59 seconds.
