The movie’s casting director thought Hennig would be a perfect fit for Blaire, bringing her in to meet the filmmakers. She booked the gig and was ready for the haunting to begin—which was unlike any other experience for the actress.
“Normally when you’re doing a film, they call action but there’s like 30 or 40 people around. With this movie, I was alone in my bedroom,” Hennig says. “Everything was different, so everything was sort of a challenge. They wrote a great story and allowed us to improvise on top of that. And that’s how we really figured out who our characters were and built chemistry with each other.”
Unfriended’s filming took place entirely in one house, with each actor in their own room being filmed in real time by their laptop cameras. When the characters on screen went to Google something or respond to Facebook messages, the actors matched the action on their own computers to help genuinely pace the movie. But this was done solely to help bring authenticity to the film. The final product of top-right corner notifications and mouse clicks that audiences get to see was made through nifty editing and a team of animators.
“Sometimes there was filming both in one week, both Teen Wolf and Unfriended, so it’d be a little confusing. Like I’d go to set and all of a sudden Blaire is aggressive and people are like ‘Whoa what are you doing,’” she laughs. “Then I’d have to remind myself, ‘Oh right, I’m Blaire today, I’m Blaire for the next two hours,’ but it all worked out and I really enjoyed playing both characters. They’re nothing alike.”
