The Purge ($3 million budget)
It’s not every day that you see a horror movie with a truly original concept, but The Purge is one of the rare few. The movie’s storyline is based on a civilization where every year, for a 12-hour window, all crime is legal. The film which starred Ethan Hawke and Lena Heady made $89 million.
The film was such a hit that it produced three sequels as well as a spin-off television series. To date, the movies have made $445 million, despite its mixed reviews.
