Orignally announced as ‘The Further’, but now called Insidious, the latest movie from Saw director James Wan (backed by Paranormal Activity producers Jason Blum, Oren Peli and Steven Schneider) looks like it could be pretty effective, or unbelievably silly, we can’t decide quite which. Patrick Wilson and Rose Byrne star as a couple dealing with the fact their son has fallen into a coma. However this is no ordinary coma, as evil supernatural entities are keeping the child’s consciousness in a realm called The Further, and refusing to allow it to return! As a woman in the new UK trailer says, “It’s not the house that’s haunted. It’s your son.” I presume that means that at some point in the movie, Yvette Fielding and Derek Acorah will want to hold a Most Haunted vigil inside him. Insidious is in UK cinemas 6th May 2011
