This Halloween the most successful horror franchise in the world unleashes a new entry into its box-office dominating run of movies, Saw 3D.

In Saw 3D, the seventh chapter in this blood-splattered but inventive series, a deadly battle rages over Jigsaw's brutal legacy. A group of Jigsaw (Tobin Bell) survivors gathers to seek the support of self-help guru, and fellow survivor, Bobby Dagen (Horror Channel favourite Sean Patrick Flanery). Soon though, the survivors really must help themselves as Dagen’s dark secrets unleash a new wave of terror...

We've been lucky enough to catch the first 8 minutes of this and can report that the 3D photography looks amazing and that this could be the strongest Saw yet.

Click below for the brand new teaser trailer and Saw 3D will be in cinemas October 29th.
