In the new film…
Bodies are turning up, and they’re linked to Jigsaw — or a Jigsaw copycat.
The new chapter in the long-running saga has been rated “R” for “Grisly Bloody Violence and Torture.”
We understand that neither Costas Mandylor nor Cary Elwes will be returning to play their respective characters, who both ended up becoming Jigsaw apprentices in earlier installments. As for the original Jigsaw himself, Tobin Bell will be back in some capacity.
The cast also includes Mandela Van Peebles, Laura Vandervoort, Brittany Allen, Callum Keith Rennie, Matt Passmore, Hannah Emily Anderson, Josiah Black, Shaquan Lewis, Michael Bolsvert, and James Gomez.

Jigsaw features plenty of the deadly traps for which the franchise is famous. “We’ve got some pretty wild traps in the film — we don’t shy away from the gore,” says Michael Spierig. “It’s such a perfect Halloween scarefest. It’s perhaps not quite as vicious and more fun, which is something we tried to inject into it. But it’s still full of good fun gore, that’s for sure. And, on top of that, it’s got a really great mystery, and there’s very interesting twists. It’s Saw for 2017.”
