Continuity mistake: When Bond is talking to Mathis at a table at the cottage in Italy, pay attention to the watch on Mathis' wrist. First it faces the side of his wrist because that way it is best shown on screen, but in the next shot, still at the table, it suddenly faces the outside of his wrist like watches are usually worn.
Continuity mistake: When Bond is on the plane with Mathis, and asks the waiter for his usual drink, between shots, Mathis' hair changes - in some shots there's a lock of hair on his left down by his eye, in some shots he's got two bits of hair loose on his right, and in others his hair's all in place. All this without him ever touching it.
Continuity mistake: During the fight scene at the Hotel Dessalines with Slate, Bond and Slate go through glass pane doors and land on the terrace, and Bond kills Slate. Notice that at first there is a broken piece of wood pane laying next to Slate's head; the next shot shows no wood pane, and there is a door knob that wasn't laying close to Slate's head in the first shot.
Continuity mistake: At the beginning the roadway openings have curved arches, a very short straight section with rectangular openings, then more arches. When the driving begins, the arches have disappeared and the entire sequence is on a very long curved section with rectangles, before they get to the open road.
