‘Insidious: Chapter 2′ Interview: James Wan and Leigh Whannell on How to Make a Sequel Even Scarier

Director James Wan and writer Leigh Whannell are responsible for one of the biggest horror franchises of all-time with the 'Saw' movies. Since then, they've created yet another horror franchise as 'Insidious: Chapter 2' opens in theaters this Friday. We caught up with Wan (who also directed this summer's 'The Conjuring') and Whannell to talk about creating the follow-up and how exactly you make a scary movie even scarier.

'Insidious: Chapter 2' is the "terrifying sequel to the acclaimed horror film, which follows the haunted Lambert family as they seek to uncover the mysterious childhood secret that has left them dangerously connected to the spirit world." The film brings back stars Patrick Wilson, Rose Byrne and Lin Shaye and promises to get you all ready for the upcoming Halloween season.

As Wan heads off to direct 'Fast and Furious 7' (filming starts this week), we spoke with him and Whannell, his long-time collaborator, on how they listened to the fans (and the critics) of the first film and how they think they've created something we haven't yet seen in a horror film.

'Insidious: Chapter 2' hits theaters on September 13.
