I love spoilers. I read them when I see a movie AND especially when I don't. I won't go into the details of the new Saw IV movie, but the best and most detailed spoilers are on Wiki (no surprise).
Of interesting note is the new Saw IV movie in which Tobin Bell (Jigsaw) is shown to be DEAD. There is an autopsy scene in the trailer that shows him, cough cough, out of the picture (I so funny). Reader, I am not giving away anything here, it is in the trailer, please don't scream.
The obvious question is how they are going to produce another saw movie without Jigsaw. The easy answer is a prequel or that he has trained others in the Jigsaw method - meh, too straightforward. Here is the even better answer in a movie that prides itself on twists - wait for it - Jigsaw has a twin (gasp, yes it gets better).
Not only does he have a twin, he is one of three triplets. Three little Tobin Bells.
How do I know? Someone higher up on set was shooting off their mouth and a little bird overheard it.
There I said it.
