During the bombing scene in the first ten minutes of the film, the plane first shown as a bomber hunting in the fog for the S.S. BOMBAY is a Douglas DC-3, an aircraft that was used during the Second World War exclusively by the Allies, and then only for personnel and freight transport, never for bombing. Moreover, even if it could have been modified into a bomber, it is unlikely that a DC-3 would have attacked shipping from Allied countries. Additionally, during the course of pursuing the ship, the DC-3 inexplicably transforms into a smaller aerobatic plane, which strafes the ship with machine-gun fire, after which it transforms back into a DC-3 and drops its bombs on the ship (but misses it).
A shadow of the camera is visible on the front of the bar as it moves in close to the bar as the bartender gulps down the two drinks after the bombing raid on the ship.
When Dan and Diana are in the bungalow, they are sitting on the couch when there is a knock at the door. It is then a shadow of the boom microphone can be seen moving on the curtains behind them.
