The Saw horror movie franchise is getting a place in the Guinness World Records as the most successful horror movie series, says one of the film's producers, Mark Burg.
"I'm still in shock," Burg said. "The fact that we beat out [such horror franchises as] Friday the 13th, Nightmare on Elm Street, Halloween and Texas Chain Saw Massacre is a testament to our cast, crew and our partners at Lionsgate."
The franchise consists of six movies, each one coming out consecutively every Halloween since 2004. The seventh, and final, instalment is due out October 29 (in the US) and will be featured in 3D.
Collectively, the Saw films have made more than $US730 million ($820 million) at the worldwide box-office and sold more than 30 million DVDs, according to distributors Lionsgate.
The films centre around a killer named Jigsaw who puts his victims through psychological torture before killing them.
Burg said it was during the production of Saw 2, that the producers decided to "etch out" one long story spanning seven films. Therefore, after the seventh movie, called Saw 3D, there will be no other movies, including spin-offs or prequels.

"We are done; this is it," he said. "We don't want to be that boxer who fought one too many fights."
Burg said the seventh chapter was always "anticipated" by fans as the final one.
"In every Saw movie, we left questions open and in this movie we answer every question the audience has ever had," Burg said, adding that even new viewers will be able to follow and "get caught up to speed".
The Guinness presentation will take place at San Diego's Comic Con convention on Friday. London-based Guinness editor-in-chief Craig Glenday will be on hand to present the award to the film's producers.
