Hidden

The role of John was initially cast with another actor who dropped out a few weeks before filming began. The producers attempted to recast the role but couldn't find an actor who was willing to commit to the location and shooting schedule. As a joke, Nick Nielsen called his friend from college theater, Rob Davenport, and asked him to fly all the way from Texas to Washington, a week before principle photography, to shoot the film. Rob Davenport took him seriously and bought the plane ticket right there. Nick Nielsen said that had his friend not agreed to it that he would have had to cancel the entire production.

After the credits there is an outtake of one of the crew members phone going off during an intense scene with Lars threatening John with a knife.
