Fear of the dark is conducive to horror. It’s elemental in its simplicity. A darkened room, a flickering hallway, a shady alley – all naturally provoke an instinctual fear of the unknown. Horror films expertly tap into this fear, playing with what exactly lurks down that darkened hallway, alley and (most terrifyingly) in your own room. InDavid Sandberg’s2013 horror shortLights Out, a woman is terrorized bysomethinglurking within the darkness of her home. The catch – thissomethingonly comes out when she shuts the lights off. The short runs less than three-minutes but somehow manages to be more unsettling and frightening than most ninety-minute features.It’s available hereand well worth your time.
Sandberg’s short drew the attention of horror mavenJames Wan(The Conjuring) and now three years later, Sandberg has directed a feature length version. At the WonderCon panel forLights Out, Wan andLawrence Grey(serving as producers) and director David Sandberg, alongside starsMaria Bello,Gabriel BatemenandCharlotta Lostenpreviewed what to expect from the horror film. For highlights from the panel, read below.

Panel Highlights:
Wan stated the appeal of producingLights Outstarted with the filmmaker. “I’m always excited when I can discover new filmmakers” Wan said, “With my production company Atomic Monster, I want to give new filmmakers the chance to do what I did [withSaw].”
Per Wan: “What I love about the concept [ofLights Out] and what I love about the script is that it’s a fun movie. I want to start off making the kinds of films that I loved growing up as a kid. Fun horror films that are scary but at the same time after you finish the movie, it leaves you excited to see more. That was the criteria.”

A year ago David Sandberg was living in an apartment in Sweden. It was surreal to suddenly get a call to fly to Hollywood and turn his short into a feature.Lights Outwas the first time Sandberg had ever “set foot on set as the director of a big budget Hollywood film”.
On developing the concept ofLights Out: Sandberg offered, “In a lot of films you have a kid who has an invisible friend… I thought it would be more scary if it was the parent who had the invisible friend.” It was from this kernel that the rest of the story came from.

Maria Bello described her terrified reaction to seeing the movie the first time a couple days ago. “I watched the movie between my fingers” she admitted, “I knew what was going to happen and I was still scared.” On what drew her to working with a first time filmmaker, Bello stated that it was the drama that drew her in. “For a horror film, it’s such a drama – a family drama. Bello described her character Sophie as “a schizophrenic suffering mental delusions. It was hard to play someone who loves their children but at the same time is tormented by her own demons.”
David Sandberg citedThe Shiningand James Wan’s own films as the primary influences onLights Out.
What advice did James Wan offer to the first time filmmaker before he started shootingLights Out? “I just told him to have fun with it” Wan offered, “Just trust your own instinct.”
Having James Wan on set helped Sandberg to accomplish his vision. He recalled one instance where a character only has a candle for a light. Sandberg wanted to shoot the scene with only candlelight. Production though quickly shot the suggestion down, stating it would be impossible to shoot the scene with just a candle. Later when Wan was visiting set, before the scene was shot, he offered that maybe it would be better to shoot this scene with just candle light. Of course immediately everyone agreed with Wan and said let’s do that. “So having James [on set] was good in that way” Sandberg joked.
