Saw IV (2007) was given the green-light before the third movie even opened. This was stated in Fangoria Magazine #257: "The synopsis, bare as it is, takes the third installment to a new budget level for Lionsgate's wildly successful franchise. Saw (2004) was made for approximately $1 million, Saw II (2005) cost $4 million and the figure for Saw III (2006), according to producer Mark Burg , has risen to $10 million. Saw III was green-lighted the morning after Saw II opened to massive box-office returns, the producer confirms, "and when they ordered Saw III, they also ordered and green-lit Saw IV."
