Visible crew/equipment: During the scene where Nick and Sam come upon Richard having a midnight snack in the kitchen you can see a small bright whitish reflection of some kind of equipment in the top left (our left) kitchen window, down in the lower right corner. There is no character movement or other scene related explanation for this reflection. It moves and fades during the scene, most dramatically at the end of the scene.
Visible crew/equipment: Early morning jogging scene with Kevin Kline and William Hurt. As they are walking towards the camera on Hurt's left side, our right (the side closest to Klein). Level with Hurt's waist the wiring to his power pack working his mic is visible. Confirmed in DVD extras.
