The Paranormal Activity franchise has been one of the single biggest movie success stories of the twenty-first century so far. The original movie was completed in 2007, but its creators had to wait until 2009 for a theatrical release. Presented in a simplistic, "found footage" style, the film was independently developed and, thanks to its small budget, went on to become the most profitable movie ever made after Paramount acquired the rights. Given the great financial results and positive critical response it generated, a sequel was almost inevitable and Paranormal Activity 2 was subsequently released in 2010.
