Following a very successful opening weekend at the box office, Universal Pictures is moving forward with a sequel to The Purge. Jason Blum is returning to produce the follow-up, although no cast members have been confirmed.

The sequel has already gotten conditional approval for a $2.25 million tax credit through California's Film and Television Tax Credit program. However, in order to secure this credit, shooting must begin by the end of this year, at the latest, and the production must meet several other requirements.

The Purge starred Ethan Hawke and Lena Headey as parents in a gated community who try to survive the annual event known as The Purge, where all crime is legal for a 12-hour period. James DeMonaco wrote and directed this thriller, but it isn't known if he will return to the helm.

The Purge was produced on a budget of just $3 million, so, with a $2.25 million credit waiting in the wings, don't be surprised if The Purge 2 gets a substantial budget increase.
