Universal and Blumhouse PIctures announced that a sequel to The Purge (which doesn't have an official title at the time of this writing) is going to open on June 20, 2014.
Returning alongside James DeMonaco (who will write, direct and produce) the next chapter of the thriller are Blumhouse Productions’ Jason Blum, alongside Sébastien K. Lemercier and Platinum Dunes partners Michael Bay, Brad Fuller and Andrew Form.
No word yet as to where the next chapter will take us. There was earlier buzz that the sequel might be called The Zone, but branding is everything so I can't imagine they'd take "The Purge" out of the title.
