Last year's The Purge set up a fairly ridiculous premise for what amounted to a home-invasion movie, but it brought in big bucks at the box office, especially in comparison to its modest budget, and so a sequel is forthcoming.
As our own Eric D. Snider explained in his review of the first film:
The premise is that in the not-too-distant future, America has almost no unemployment and very little crime. (No, that's not the implausible part.) What either led to this or is how it is maintained -- the movie isn't clear on which came first -- is The Purge, where all crime, including murder, is legalized once a year for 12 hours. During that time, you can do whatever you want (using up to a certain class of weapon) to whomever you want (up to a certain level of political standing) without legal consequences.
(You can read the entire review here.)
James Monaco, who wrote and directed The Purge, has performed the same duties for the sequel, The Purge: Anarchy, starring Zack Gilford, Frank Grillo, Michael K. Williams, Kiele Sanchez, and Carmen Ejogo. The first trailer has been released; whereas the original film confined much of the action to a secured home in a gated community, the sequel moves the action outdoors, where an unlucky couple have car trouble at the worst possible time.
You can watch the trailer below. The movie will open in theaters in North America on June 20.
