When the salvage worker discovers the pile of scrap metal that Jaime had stacked in less than a minute, he stares in astonishment and then sets the piece of iron he's carrying on top of the pile. Yet in the next close-up shot of the pile, the new piece of scrap is gone.
The chain that Jaime breaks off from the hatch-wheel is laid differently in the shot of the chain breaking as opposed to the shot of the hatch opening.
The villains spin the hatch-wheel several revolutions to extend the hatch-latches before they chain the wheel, yet when Jaime forcibly turns the wheel just a fraction of a turn to break the chain, the hatch opens up right away, without her having to spin the wheel around any farther.
The last piece of scrap steel plate that Jaime is seen to load onto the pallet is a large squarish fragment with four right-angle corners and straight sides. Then a final clink is heard, apparently the sound of her loading one last plate onto the stack, and then the shot of the loaded pallet shows the top piece as being a very large rectangular sheet with an inward-curved gap from a "broken-out" corner. Then when Bobby strolls back and discovers that the plates have all been loaded, the broken-out-corner piece is gone from atop the stack, the neat square piece is now on top, and Bobby is carrying the broken-out-corner piece.
Jaime arrives for work in the morning, yet when Bobby instructs her to leave the heavy lifting to him, the lighting is obviously the golden-orange glow of late afternoon.
Duke tells Jaime that after finding the location of the money-bag, he chalk-marked the spot on the ship with a big "cross", yet when the villains and Duke and Jaime arrive at the spot in question, it is marked with a small white chalk "X", not a big cross.
When Duke is standing and watching the villains flounder around in the water, he is standing without his crutch.
Bobby is a long-term and avid animal-lover, so he would never leave the sharp-edged cut lid from the cat-food can in the cats' dish.
