Once I got over the fear of writing female characters, it actually came quite easily and I was really happy with it. I just thought about girls I knew really, really well and I'd just have conversations with them and tried to relay how they talk about certain things.

The one negative to horror is that it's always law of diminishing returns. When you go in the funhouse, the ride is never scary the second time. You will never have that pure experience as when you first watch it.

My parents love it! They're on set. They make cameos in the movie. My father is a psycho-analyst and a professor at Harvard and he told me how many of the other professors at Harvard have gone and seen it. They love 'Hostel' and they love the thought behind it.

I was listening to music to kind of pump myself up and get psyched up, like I was listening to Iron Maiden and Misfits and Dead Kennedys, and it was like my '80s Massachusetts parking-lot heavy metal and Guns N' Roses.

There's something very scary about exposing yourself on camera, knowing that you're going to be put on thousands of screens around the world for everyone to judge, but there's also something very thrilling and exciting about it.

You have to write scenes and design scenes that are scary and horrific, but that are also watchable. I didn't want people to just feel like they got punched in the stomach.

I generally follow my own compass and make films about what's scaring me.
