For all the vitriol and criticism that the Saw franchise acts as a magnet for, with the films being seen as a poster child for all that's wrong with modern day horror movies (although there's clearly a case in there, which has been debated many times over), the series is still arguably the best-marketed movie franchise on the planet. It matters not that, seemingly without fail, the films get hit by reviews the wrong side of generous - every year, Saw mops up at Halloween in cinemas, and then does so again when the DVDs come round.

Unsurprisingly, therefore, Saw VI is heading to cinemas this October, and once more, Lionsgate has put together a slick promo trailer to tease the upcoming film. This year's gimmick seems to be surround the number six quite a lot given the trailer's content, which actually tells you very little, short of letting you know that the film exists. Which, of course, is the point of the exercise.

Meanwhile, just in case you're sat there thinking that it's all well and good having Saw VI this October, but what are you going to do the year after, Lionsgate has come to your rescue. It's confirmed that - yes! - Saw VII is heading into production in January of 2010, ready for its usual Halloween release slot. Brilliantly, this time the film is being directed by the production designer of Saws 2 to 4, David Hackl, who also helmed Saw V. Rumours that the work experience kid might get the gig if this all carries on for another decade have not been commented on.

Anyway, enough of that. The teaser trailer for Saw VI follows these words, and by the magic of the Internet, you should be able to press play and enjoy...
