Class Action Park

1h 30m · 2020 · Directed by Seth Porges · 3.3 / 5 on Letterboxd

Class Action Park (2020) runs 1h 30m, directed by Seth Porges. It is one of 3,647 films in the 100 Minute Movies catalog — every one rated 3.0 or higher by Letterboxd members and short enough to finish in an evening.

Class Action Park explores the legend, legacy, and truth behind the 1980s water park in Vernon, New Jersey that long ago entered the realm of myth. Known for its dangerous, unsupervised rides and lack of regulation, guests of Action Park expected to walk away with injuries and were lucky if they made it out alive. Shirking the trappings of nostalgia, the film uses investigative journalism, original animations, recordings, and interviews with the people who lived it to reveal the true story of Action Park.
