Revealing mistake: At the end of the movie after Necros falls from the plane the camera cuts back to Bond, as he tries to struggle his way out of the nest. If you look closely under the nest you can see Necros at the start of his fall again. Also notice Necros is replaced by a dummy.
Revealing mistake: When Necros fights for his life on the plane and later when he plummets, one can see a protruding, bulky object under the stuntman's shirt, which is obviously his parachute.
Revealing mistake: During the scene at the airbase, several explosions take place one after the other in a straight line. When the smoke disappears, one can see the track of the protruding mount where the pyrotechnics were buried.
Revealing mistake: When Bond drives on the frozen lake, there are mounts of snow to hide the explosives from the rockets fired at by the enemies.
Revealing mistake: Saunders is not in the door-way when the bomb launching the glass door goes off. He actually jumps forward to get there in time to get caught.
