6. Saw (2004) Saw is an attractive brand for horror movies. To create such a thriller, James Wan and Leigh Whannell have worked together for a long time to write a script with the lowest cost because they thought no one would invest millions of dollars for two young filmmakers. They only had $ 10,000 and decided to make a movie with simple context and a few actors. The script focused only on two men chained in a dirty bathroom with a corpse in the middle of them. Although in the end, the capital was raised to 1 million USD, the content remains unchanged.
