Fans can re-live the sheer terror from director James Wan' Saw when the modern horror-classic is re-released in theaters for one week only, starting October 31, to celebrate the 10th Anniversary of its initial release. Five years before Paranormal Activity helped spawn the "micro-budget" genre, Saw took audiences by storm, with this thriller that cost just $1.2 million to make, taking in over $100 million worldwide, and spawning a franchise that included six successful sequels.Saw starred Leigh Whannell (who co-wrote the script with James Wan) and Cary Elwes as two strangers who wake up trapped in a horrifying dungeon, as they are forced to follow the intricate rules of a killer known only as Jigsaw, if they want to make it out alive.To help celebrate this 10th Anniversary re-release, we have a giveaway lined up where fans can win five Saw collectible posters, three of which you can see below, with two more debuting over the next two weeks, and a number of branded items such as stickers, t-shirts, key chains, postcards and bracelets.What are you waiting for?
