The first film in the series was a surprise box office hit, with its sequel doing even better business. So, unsurprisingly, a third Insidious film is due for release next summer and the first trailer has dropped. 

This time there's no Patrick Wilson and Rose Byrne, with lead duties falling to Dermot Mulroney and Hayley Kiyoko while original scripter and star Leigh Whannell steps behind the camera for the first time to direct. 

Looks decent. Looking forward to this
