Soon to be revealed as one of my top 10 of 2010, James Wan and Leigh Whannell’s Insidious (review) premiered at this past September’s Toronto International Film Festival. Since then all that was released is this clip and this image. Now, sales company IM Global has released the following promo poster, along with a new image. Sony Pictures acquired the Poltergeist-esque horror flick that’s being retooled for a 2011 release. In the film a young family makes the terrifying discovery that the body of their comatose boy has become a magnet for malevolent entities, while his consciousness lies trapped in the dark and insidious realm known as The Further.
