(Pocket-lint) - The Purge Universe is one of the most successful horror film franchises of all time.
The original movie, The Purge, which debuted in 2013, made $90 million at the US box office on just a $3 million budget. That was good enough for it to spawn a universe consisting of three sequels, a prequel, and even a TV series. As of right now, the entire franchise has brought in over $6.2 billion worldwide.
The synopsis behind The Purge Universe centers around an alternate version of the US - where once a year, for one day only, all crime is made legal. Perhaps making the situation even scarier, most of the purgers (aka the people doing all the killing in this dystopian reality) wear grotesque masks while committing their acts of violence. The films also tend to focus on a group of characters who are preparing for and trying to survive the 24-hour purge period.
