4) Go deeper
"What’s scary to me isn’t a ‘jump’, but something that affects you on a deeper, psychological level, altering the way you think about your life and your world.
"Something that really leaves an imprint."
5) Be careful with the casting
"We auditioned over 150 people because they’re the most important thing – they are the movie.
"If you don’t believe them as real people, you’re not going to care about them, you’re not going to connect with them and nothing else is going to matter.
"With Katie [Featherston] and Micah [Sloat] they had great instincts, and were very quick and smart as far as coming up with dialogue. There were no lines – it was all their own words."
6) Keep the budget small
"Having such a low budget really helped because I couldn’t go crazy with special effects, which I think in the end would have actually been a detriment to the movie. And I had to be creative."
"If you think about it, I was trying to be authentic to how this would be if it were true, if it were just a couple around the house with a camera."
