Following test screenings of Skew, it was decided that additional scenes would need to be filmed. This decision was complicated by the fact that Amber Lewis (who plays Eva Hansen) was eight months pregnant at the time. Reshoots involved filming Lewis behind open car doors, placing objects in front of her baby bump, and shooting her reflection through the car's side view mirror. The new (pregnant) footage made it into five different scenes of the final film.
The location for the phone booth scene wasn't discovered until mere hours before the shoot when a production assistant was sent out to find an adequate setting. Not having a generator to connect to for an additional light source in the middle of the night, the crew used the closest available power source - a nearby house. The homeowner slept through the entire shoot.
The final motel room scene was filmed in the script supervisor's apartment. The script supervisor also plays the character of the convenience store clerk.
Schelenz purposely shot the film in chronological order so that the characters' facial hair would grow without interruption, the actors would become agitated and tired of one another, and Rob Scattergood would learn to operate the camera more fluidly. Although Scattergood doesn't appear on camera, he grew out his facial hair in order to stay true to character.
It took several hours of training to have the deer stand in one spot during the tour bus scene.
