For me personally, the most exciting sequels are the ones that bring back the key creative core group behind the original film, and in the case of 'Insidious: Chapter 2,' there's reason to celebrate because just about everyone is back! Director James Wan (who has never done a sequel until now), writer/actor Leigh Whannell and cast members Rose Bryne, Patrick Wilson, Barbara Hershey and Lin Shaye are all back in the fold along with some other new interesting faces in the mix like 'The House Of The Devil's' Jocelin Donahue playing a young Barbara Hershey! So why did Wan decide to follow up 'The Conjuring' with a sequel to his surprise hit from 2010? Check out our interview with him and Whannell to get the scoop. 'Insidious: Chapter 2' opens in theaters September 13th!
