STATUSDisputed

The Patterson–Gimlin film is a 59-second, 16mm colour motion picture filmed on 20 October 1967 at Bluff Creek, California, by Roger Patterson and Bob Gimlin, purporting to show a large, hair-covered, bipedal creature — nicknamed "Patty," a feminised version of Patterson's own surname — walking along a creek bank before briefly turning to look toward the camera.[1] It remains the single most widely recognised and cited piece of purported Bigfoot evidence, and one of the most analysed and disputed pieces of film in the history of cryptozoology.[2]

The filming

Patterson, a Bigfoot enthusiast, and Gimlin, a horse trainer, set out on horseback into the Bluff Creek area of Northern California to investigate reported tracks, carrying a rented 16mm camera and around 100 feet of film.[1] According to their account, they encountered the creature at close range along the creek, with Patterson dismounting to film freehand while his startled horse reared.[1] A single frame from the footage, numbered 352, subsequently became the most widely reproduced still image associated with the film and with Bigfoot more broadly.[3]

Scientific and forensic analysis

The film has been subjected to repeated formal analysis. Forensic examiner Jeff Glickman published a detailed study, "Toward a Resolution of the Bigfoot Phenomenon," in 1998.[3] In 2013, primate anatomy specialist Jeffrey Meldrum and visual effects specialist Bill Munns published a technical paper specifically addressing the film's image integrity, examining questions including the subject's apparent gait, shoulder breadth, and soft-tissue movement against what would have been achievable with 1967-era costuming techniques.[3]

The Heironimus hoax claims

In the early 2000s, Bob Heironimus — a Patterson acquaintance from Yakima, Washington, who had supplied some of the horses used on the Bluff Creek trip — came forward publicly claiming he was the person who wore a costume in the film, some 32 years after the footage was shot.[1] Heironimus said he was offered (though, he says, never actually paid) $1,000 to wear the suit, and described adding bulk beneath it using a football helmet, football pads and hip waders.[1] His account has some documented inconsistencies — Heironimus has given differing descriptions of what the suit itself was made from across different tellings — and researchers attempting to recreate the costume from his description have produced results that do not closely resemble the creature seen in the film.[1] Journalist Greg Long's 2004 book The Making of Bigfoot compiles Heironimus's account alongside interviews with Philip Morris, a costume maker who stated he sold Patterson a gorilla suit shortly before the filming and gave him advice on customising it for a longer-armed, broader-shouldered appearance, along with several Yakima residents who said they saw the suit in Heironimus's possession afterward.[4]

Accounts differ on exactly who approached Heironimus about wearing the suit. Heironimus himself has stated it was Gimlin who first raised it with him, quoting Gimlin as saying Patterson "needs someone pretty good size to get in the suit."[5] Gimlin himself has consistently and publicly denied any involvement in a hoax, maintaining — as the only surviving participant in the 1967 filming — that he and Patterson genuinely encountered an unknown creature.[5]

Capturing Bigfoot (2026)

In March 2026, the documentary Capturing Bigfoot, directed by Marq Evans, premiered at the SXSW Film & TV Festival with new claims challenging the film's authenticity.[6] The documentary centres on a reel of 16mm film discovered in 2022 in the safe of a deceased former Boeing film-lab worker who had been socially connected to Patterson and Gimlin; the footage, apparently shot roughly a year before the famous 1967 film, shows a different man in a fur suit alongside Gimlin on horseback in terrain more consistent with Washington state than Bluff Creek, California, suggesting a possible rehearsal or dry run.[7] The film also features Roger Patterson's son, Clint Patterson, stating that the 1967 encounter was staged and that he personally witnessed his father burning the costume afterward, and identifies Al DeAtley — Patterson's brother-in-law and a financier of his film work — as the man in the fur suit shown in the newly surfaced rehearsal footage, rather than Heironimus.[8]

Reaction has been divided even among Bigfoot researchers and believers who attended early screenings; some described the new material as effectively conclusive, while others noted that independent, transparent forensic examination of the newly surfaced footage had not yet taken place at the time of the film's premiere, and that questions remained about chain of custody for the material.[9] These claims should be treated as a significant, but still recent and not yet independently verified, development rather than a settled resolution to the case.
