After The Conjuring: Last Rites' record-breaking box office opening, it's not surprising to hear more movies could be on the way – even though this installment was billed as a final outing.

Last Rites has made $194 million at the global box office since it was released on September 5, making it the biggest horror opening ever (2017's IT previously held the record with $190 million).
