Movies that heavily rely on action and violence require plenty of stunt doubles, time, and preparation. To successfully make these films, incredible precautions are taken to ensure the safety of the cast and crew, while simultaneously shooting a movie that will wow audiences with amazing stunts and special effects. Ordinarily, most movies go off without a hitch, even those with heavy doses of special effects and over-the-top stunts. However, there are some films that have proven to be immensely more dangerous to make than others. These are the films that directly put the cast and crew in harm's way, with some of them even costing people their lives.

See the movie where a lack of care for safety resulted in a deadly helicopter crash.

Waterworld Was Almost A Watery Grave

Universal Studios

Released in 1995, Waterworld was primarily shot in the Pacific Ocean off of the coast of Hawaii. The unpredictability of the weather and the waves almost took the lives of several members of the cast, crew, and even the star.

On one occasion, the film's star, Kevin Costner, almost died when he was caught in a freak storm for 30 minutes while tied to the mast of a boat. On top of that, his stunt double, Laird Hamilton, had to be saved after being lost at sea while "commuting" to the set on a jet ski. Set pieces were sinking; boats were falling apart, the entire production was a nightmare.
