A new trailer for Insidious has just come out and it looks scarier than ever. There have been three previous movies throughout the past 7 years. The Last Key will be the last of the Insidious movies. From the looks of the trailer it will be a good way to wrap it all up. There is no set date just yet as to when the movie will come out but sometimes next year in January. Until then check out the trailer and leave a comment on if you would watch it.
