Continuity mistake: The girl named Why is in the bathtub. Frédérique brought her a cup of tea that she indignantly put aside because it had an excess 1/2 sugarcube. She put the cup to the edge of the tub with the spoon facing one direction, but during the conversation the spoon turns 180° on its own during a cut. (00:07:40)
Continuity mistake: During the opening credits, Charles Bronson is walking along the pier, carrying his bag over his left shoulder. He stops in a separate shot, grinning at the camera and tossing the highball glass he was carrying into the sea (as soldiers normally do). In this same shot, he switches the bag to his right hand. Back to the previous angle, and Bronson is again walking with his bag over his left shoulder, like nothing happened. (00:01:15)
Continuity mistake: The ford transit van used by the demolition men Ron and Mr Perry changes between scenes from a long wheelbase van reg no. KGX107D to a standard van reg no. OYO576F.
Continuity mistake: When we see Norman standing by the desk in his boss' office, you can see there is nothing in front of the boss on his desk, but when we see the boss in the next shot, a piece of paper suddenly appears.
Continuity mistake: Joe Bass, freshly robbed by the Indians, is asking the slave "You come a long way from home, you ran away?" In his hand is a bottle of liquor with the cork on. Change shot, the bottle is open. New change, and now the bottle is closed again. (00:08:00)
