What are the key elements in 'The Shallows' that are based on a true story?

In 'The Shallows', the central element based on a true story is the shark - human interaction. Real - life has shown that sharks can be unpredictable when they come across humans in their territory. The movie also reflects the reality of the vastness of the ocean and how a small human can be at the mercy of nature. The surfer's struggle to stay alive against the shark is a key element. It shows how in real - life, when faced with such a powerful predator, a person has to use their wits and any available resources to survive. The isolation on the rock in the movie also mimics real - life situations where people might be stranded and have to fight for their lives.

The main key element is the shark encounter. In real life, shark attacks on humans do happen, especially when humans are in the shark's natural habitat like in the ocean while surfing or swimming. Another element could be the feeling of isolation and the struggle for survival which many people in real - life dangerous situations experience.

One of the key elements from the true story in 'The Shallows' is the danger presented by the shark. Sharks are known to be apex predators in the ocean, and real - life shark attacks have occurred. Also, the concept of being alone and having to fend for oneself in a dangerous situation is a key part. In the movie, the character is alone in the ocean facing a shark, which is similar to how people in real - life survival situations might feel when they are alone and in danger. Additionally, the fear factor associated with sharks is very real in life, and the movie plays on that by showing the character's constant fear of the shark.
