With the horror film “Honeymoon,” Leigh Janiak gives us one of the strongest directorial debuts I have seen in a while. It stars Harry Treadaway and Rose Leslie as Paul and Bea, a newlywed couple who spend their honeymoon at a beautiful cabin overlooking the river only to see their new beginning descend into chaos as sinister forces begin to tear them apart. For a first-time filmmaker, Janiak never takes a wrong step as she generates strong levels of suspense and horror and succeeds in maintaining them all the way to the movie’s infinitely creepy conclusion.

Janiak dropped by the Four Seasons Hotel in Los Angeles, California for the “Honeymoon” press day just before the movie was released. She studied creative writing and comparative religion at New York University, and then she later enrolled in a doctoral program at the University of Chicago which dealt with modern Jewish studies with an emphasis on violence and identity in post–World War II Hebrew literature. It was there her interest in movies skyrocketed after she met a group of student filmmakers known as Far Escape Films. As a result, she dropped out of her doctoral studies and moved to Los Angeles to pursue a career making movies.

Many wondered what horror movies inspired “Honeymoon” as well as which ones are her favorites. In regards to inspirations, her answer was a bit of a surprise.

“Well certainly ‘The Invasion of the Body Snatchers’ is the most kind of thematically influential on it,” Janiak said. “‘Rosemary’s Baby’ and ‘The Shining,’ those are kind of my favorite horror films generally. I like grounded horror where you really spend time with the characters and you get to this place of uncomfortableness.”

For myself, I was very interested in finding out how she maintained the suspense throughout “Honeymoon.” I kept waiting for the movie to make a wrong turn which would ruin everything which came before it, but that never happened. For a first time director, she really kept us on the edge of our seats throughout in a way I didn’t expect. I asked her how she managed to accomplish this feat.

“I think that the reason that works is because Harry and Rose’s characters are each transforming in different ways,” Janiak said. “So it was only challenging in so far as knowing that Rose would be on one page for her character internally and Harry is on a completely different one. We have to make them still interacting and keeping these things from one another so we recognize that as an audience we sense the unease. We sense things are going wrong with each of them even though we don’t know what and just making it feel like ‘okay enough. We know something secret is happening.’ It was just about balancing their transformations.”

After the interview ended, I asked Janiak which version of “Invasion of the Body Snatchers” she likes the best. There have been four different cinematic adaptations of Jack Finney’s novel “The Body Snatchers,” the most recent being the 2007 movie “The Invasion,” and she said she enjoyed the first two versions the most but the one with Kevin McCarthy, the 1956 version directed by Don Siegel, is her favorite

Here’s hoping that we get to see many more movies from Leigh Janiak in the near future. “Honeymoon” is now available to own and rent on DVD, Blu-ray and Digital.
