More often than not, the manner in which people are introduced to one another is a commonplace occurrence. You might meet through a friend, work together, or meet by going to school together.

But for Aaron Cadieux and Carlston “Chops” Wood, it was the possible existence of a 10-foot-tall, brownish-haired, bipedal, humanoid swamp creature named "Hockomock Harry" that brought the two together.

Cadieux, a documentary filmmaker, wrote and directed “The Bridgewater Triangle.” After two years of public screenings, the documentary had its final theatrical showing on Friday night in front of a crowd of about 40 in the Wareham High School auditorium. The film explores the urban legend of a geographic triangle located in Southeastern Massachusetts, in which numerous unexplained phenomena have been reported.

Wood, a musician and resident of Wareham, arranged Friday's film screening. He is also featured in the film, telling of his childhood encounter with a Bigfoot-like creature that he claims to have seen in West Bridgewater's Hockomock Swamp. The creature was eventually given the name of "Hockomock Harry" by others who also said they saw it. Years later, Wood wrote a song about his encounter, which his band performed as an opening act of Friday's screening.

Cadieux and Wood first met in 2011 on the studio set of Tim Weisberg's "Spooky Southcoast" radio show while the show was airing its annual October episode about the urban legend of the Bridgewater Triangle. Wood's encounter with the Bigfoot landed him a guest spot on the show, while Cadieux was there conducting research for his film.

“Afterwards, Aaron approached me and said, 'Carlston I really liked your story. I want you to come in to film you in my studio'. And I said 'Absolutely,'" Wood said.

Wood then told Cadieux about his "Hockomock Harry" song, and they worked together to make a video of the song, which was used as a promotional tool for the film. The video now appears as bonus feature on the DVD version of the documentary.

The legend of "Hockomock Harry", however, is just one of many of the unexplained legends featured in Cadieux's film. The documentary weaves a narrative told by cryptozoologists, paranormal experts, folklorists, and local residents living within the triangle area who have experienced ghostly sightings, accounts of UFOs, encounters with mysterious creatures, and evidence of Satanic rituals. Although, the supposed triangle has its epicenter in Hockomock Swamp in Bridgewater, the film explains the triangle's perimeter ranges from Abington to the north, Freetown to the southeast, and Rehoboth to the southwest.

The making of the film was a four-year effort by Cadieux, and won a handful of film festival prizes. Cadieux said the film's subject stemmed from his fascination with the spooky and the unexplained.

“Halloween is my favorite day on the calendar,” Cadieux said.

"The Bridgewater Triangle" isn't Cadieux's first film. He also made a documentary about Whalom Park, the long-operating amusement park once located in Lunenburg, Massachusetts. Cadieux says he is now working on a new project that he'd rather not share too many details about.

“I can tell you this: It's a true crime documentary that is going to rock the South Coast Massachusetts region, and eventually the country," Cadieux said. "It has the potential to go down as one of the best true crime documentaries ever made.”

Following the film, Cadieux and Wood held a Q&A session, which provoked few questions. People mostly wanted to share their admiration for Cadieux's film. One audience member announced that she was thankful that Wareham is not located within the Bridgewater Triangle.

“I really liked it,” said Wareham resident Sierra Monteiro who came to the film with her sister Jasmine. “It was quite shocking about some of the stuff. I never knew about the Satanic rituals. I never really believed in it. I thought it was just our Dad telling stories.”

Robin Rousseau, also of Wareham, said that Halloween is what brought her out to watch the film, but was spooked by the film's mention of eerie occurrences in a section of the Freetown State Forest where the pavement meets a dirt road. Rousseau claims to have had similar experiences there.

“A friend and I back in the 80s – we had got lost driving in there. We took a wrong turn. ... [It] was absolutely terrifying,” Rousseau said, “We could sense something. We just quickly turned around and went back out. Now I am afraid to drive home tonight.”
