In much the same way that McDonald’s is the world’s most successful restaurant, the Saw series has been deemed the most successful horror movie series of all time by the Guinness Book Of World Records, which recognized the franchise’s superior achievement in replication with an award on Friday. Even before Saw’s seventh and final film debuts in October (with all its attendant existential questions), the series has already netted around $733 million at the box office, handily trumping other enduring contenders like Friday The 13th and Nightmare On Elm Street. Of course, receipts have not been adjusted for inflation and so on and so on, but it’s in a book now!
