Schultz is standing in the third room (the one with the recessed ceiling-light) of Von Vulture's bunker prior to his turning around to march out the front door and operate the floodlight, yet in the next shot, Schultz is standing just inside the first room (the one with the table and the bench with the communications equipment), right next to the connecting-doorway to the second room (the one with the poster of the almost-nude "Kaiserhof" girl).
The door to Von Vulture's bunker is visible at the beginning of the movie, hinged inwards to the left, and with a bright yellow pool of light illuminating the door and spilling out onto the area in front of the doorway. Schultz also opens the door before he comes in to respond to Von Vulture's calling him. Yet in the entire sequence of Von Vulture's stewingly pacing back and forth at the beginning of the film, there is no front door on Von Vulture's bunker; it's just a heavy-framed opening in the wall.
The door to Von Vulture's bunker is wide open while he is fumingly storming about, yet Schultz has to open the door to enter the bunker after V. V. summons him.
Von Vulture states that it a quarter past six, yet Daffy sets the bomb's clock-timer to a quarter till six.
