Most recently known for "You're Next," a home-invasion thriller widely released in 2013, Adam Wingard is an Alabama filmmaker known for his genre work. "I've been categorized as a mumblecore/mumblegore filmmaker, whatever that means," he told Indiewire, "and lately I am happy to not be directing horror anthology short film."

What it's about: "A soldier on leave befriends the family of a fallen comrade. He soon becomes a threat to everyone around him when it’s revealed he’s not who he says he is."

What it's really about: "Underneath the surface its about PTS disorder and brainwashing that is not only used on our troops but how that can spread beyond to an unsuspecting American family. It's also sort of an 80's action thriller."

Biggest challenges: "For me it was adapting a more refined and steady style that I am normally accustomed to. I've always had a reliance on hand held camera work and improv acting, both of which I tried to do away with as much as possible for this film."

Any films inspire you? "The inspiration for this film was roughly based on watching a double feature of John Carpenter's 'Halloween' and Cameron's 'The Terminator.' In many ways this film is an abstraction of my own disjointed memories of being a kid in the 80's and watching R-rated films."

Cameras used: "Arri Alexa."

Did you crowdfund? "No, because I have great producers who have their own capitol."

Hopes for Sundance audience take-away: "I just want them to have a good time. Not to say this is a shallow film, but ultimately I made this film to be enjoyed."

What's next? "Too soon."
