Continuity mistake: In the scene where Long John Silver comes into the Captain's quarters to offer them all some brandy to toast the voyage, watch the glasses on his trolley. When he wheels the trolley in, all the glasses are on the right hand side. When he wheels it out (nobody but Fozzie having drunk any brandy), all the glasses are on the left hand side.Andy
Plot hole: In the beginning after Flint buries the treasure, he kills all the men that are with him. The pistols he has are one-shot pistols, so there's no way he could kill 14 men using only two one-shot pistols.
