10 Horrific Wilderness Horror Movies Based On True Events

10. Black Water (2007)

From Lake Placid, Crawl, and that harrowing scene from X, crocodiles are no stranger to the horror genre.

Although the reptiles and events in those films are completely fictional, however, those in indie Aussie flick Black Water were not.

The flick sees Grace (Diana Glen) embark on a holiday alongside her husband (Andy Rodoreda) and sister (Meeve Dermody). The trip gets off to a good start but takes a disastrous turn when they go on a fishing trip deep into a mangrove swamp. Their boat is attacked by a crocodile, killing their guide, and leaving the holidaymakers stranded on a nearby tree. With the boat just out of reach and the croc unrelenting in its hunt, Black Water is an effective and fun horror.

Alongside using real crocodiles in the production, filmmakers David Nerlich and Andrew Traucki added an extra realism to this premise by basing it on real accounts of crocodile attacks in Australia.

The main premise for the film drew upon the nightmarish ordeal that two teenagers faced on 21 December 2003. After a crocodile killed their friend, the teenagers found themselves trapped in a tree overnight while the animal circled below.

Thankfully, the teenagers were rescued.
