Visible crew/equipment: Marlowe, Joe Brody and Agnes sit talking in Joe's apartment, Carol Lundgren rings the buzzer and Joe Brody answers the door. A small explosive charge is packed in an indentation on Joe Brody's door before the spot is blown out by Lundgren's shot. The same indentation can be seen again a few moments later as a small explosive is detonated when Lundgren shoots at Marlowe in the lobby of the building. (00:56:30)????
Visible crew/equipment: When Mary leans across the drugstore counter to whisper in George's bad ear, there is a small piece of tape on the edge of the counter right in front of her hand, presumably to show the actors where to position themselves for the shot (the tape isn't visible in the other shots showing that same section of the counter).

Visible crew/equipment: When Fred kisses Peggy, a boom mic is reflected in the left side of the car.
