Directed by James Wan and written by Wan and Leigh Whannell, the flick was originally meant to be called Shhhh, but then everyone realized how silly that was, and it was agreed that Silence would be the new title. And then it got changed to Dead Silence. And now, for whatever reason, that's no good either.
As mentioned at Dread Central, the trailer for Mr. Wan's sophomore effort is supposed to be showing in front of Saw 3, so it's in everyone's best interest to settle on a name already. How about The Unnamable or The Un-Entitled?
