As I was writing 'Insidious 3' I started to fall in love with the characters and the story. I became very possessive of it and I didn't want someone else to do it.

I'm still a big believer in movie theaters, and going to see movies in public.

The good thing with 'Insidious' and 'The Further' is that it's so nebulous, this supernatural world, that it allows you to bend things. There's a lot of room, it's very malleable, like how in the second film we had a lot of time travel.

That's one of the great things about creativity. You labor away in a room, and when you're writing a film, it couldn't be more of a solitary activity or a lonelier job, but if you then write a film that gets made and goes out into the world, it kind of flies away from you. It's not yours anymore.

Freddie Kruger, Jason, Michael Myers - they're all our generation. I think the kids wanted some new guys that they could take ownership of and Jigsaw was that guy.
