"If you've never heard about Action Park, it's an impossible myth your friends are making up and exaggerating... but it was true," one guest recalled.
"I think the very reason people were attracted to Action Park was because they could get hurt; that was the allure of it," another remembered.
The park, deemed in the trailer as having "too much alcohol and not enough over-sight", consisted of three areas: Alpine Center, Motorworld and Waterworld.
Between 1980 and 1987, six fatalaties were recorded there, including three drownings in the tidal wave pool.
One 19-year-old park employee was killed when his Alpine Slide car jumped the track and he struck his head on a rock; another man suffered cardiac arrest after falling out of a kayak and coming into contact with exposed wiring, suffering a severe electric shock.
Indeed footage from the park shows park-goers being slammed around in inflatable rafts, travelling at excessive speeds in overcrowded water attractions.
One waterslide — the Cannonball Loop — was a steep enclosed waterslide with a vertical loop at the end, which as Johnny Knoxville describes in the trailer "looked like a couple of kids built it, because that's what it was."
According to witnesses, the painful looking contraption spat out its first riders covered in blood and lacerations; when the loop was dismantled, workers "found teeth stuck in the padding from the first few children."
"We would try to die for fun. Everybody almost died there," one park-goer remembered, while another recalled seeing a man almost get decapitated by a flying boat.
"It starts out with people having fun. And by the end of this, crimes have been committed, cover-ups have happened, the story hasn't been told truthfully," another claims in the clip.
The trailer closes with a woman claiming the park even had fake liability insurance in the Cayman Islands.
Knoxville's 2018 film "Action Point" is based on the real life park.
