“If it’s Halloween, it must be Saw.” That was Lionsgate’s tag line to the Saw franchise for years. It all began in 2004 when then-unknown horror director James Wan delivered a very low-budget but very grisly thriller about a new killer named Jigsaw who didn’t actually kill people… he simply set them up to kill themselves. Fine line, there. The rest was history. Wan went on to direct other iconic horror films, including Insidious and The Conjuring. Star Tobin Bell and his sidekick Billy the Puppet became as recognizable as Jason’s hockey mask. Torture porn (a bit of a misnomer for the earlier, better Saw films) became its own sub-genre. And for nearly a decade, most studio horror movie releases cleared the way for Lionsgate to drop a new sequel in October just before Halloween. However, before it became a full-blown phenomenon, director James Wan sat down with the film’s writer and co-star Leigh Whannell to talk about the original for the DVD release. Now, for the film’s 10th anniversary, it’s time to look back at this new classic and learn.
