Visible crew/equipment: When John returns to the clinic to drop off a gift for Gabriele, when the cab pulls up, for a split second, you can see what appears to be the reflection of a crew member (likely part of the camera crew) walking in the green doors right before John opens his door. (It's very hard to see, but you can see it if you pay close attention.)
Visible crew/equipment: The camera is reflected in the glass of the gas station after the woman calls the cops on the killer. It's visible on the right side before the shot cuts.
