Revealing mistake: When Bond exits the carriage at the tunnel, it's an obvious stunt double.
Audio problem: When the circus train pulls out of the station just after Bond has the shoot out in the tunnel we hear the sound of a steam train pulling away with wheel slip, but the wheels are not slipping at all.
Continuity mistake: When Bond asks for the jet's tank to be filled, his cockpit swaps from closed to open between shots.
Continuity mistake: While with Q, Bond rolls-up his sleeve to show his watch. In the close-up the shirt is further down.
Continuity mistake: When Bond approaches a gas station with the jet, in the close-up of Bond's face the background changes (cars and buildings disappear).
Continuity mistake: When Bond is about to fly through the second door of the hangar there are no soldiers holding it. A shot later a bunch of them have suddenly appeared.
Continuity mistake: When Bond is about to fly through the hangar, the soldiers are running away. In the immediate next angle they're standing still and the colonel is commanding them to run.
Continuity mistake: When Bond is about to take-off, there's a brief shot of the plane speeding up. It is obviously a different runway because a) the trees on the side have disappeared, and b) the road swaps from clean to filled with skid marks.
Continuity mistake: When Bond places the bomb inside the radar he is slightly facing backwards and twisting his arm, but a shot later he is perfectly positioned in a much more comfortable position.
Continuity mistake: During the pre-credits Bond enters a military base, knocks down a soldier and places his suitcase on a table. The position of the suitcase changes between shots.
Factual error: Bond is given a tag in Spanish, but it shows the word Col., short for Colonel. It should read Coronel.
Visible crew/equipment: When the movie starts, Bond arrives at the horse show and steps down from the car. A set of 10 stage lights are reflected on it.
Factual error: Orlov hands Khan a map "Die Umgebung Berns." Bern is the capital city of Switzerland which has nothing to do with the movie.
Revealing mistake: When Bond jumps out of Kamal's aeroplane with Octopussy, you can see that Bond is not Roger Moore but his stunt double.
Revealing mistake: When Bond sends an assassin crashing into the tank containing the octopus, you can see the assassin is a dummy.
Other mistake: When Bond starts up his plane during the pre-credit chase scene, the Cuban forces are visible at the horizon closing fast - they have to be to keep the tension up - but with the closing speed and the time it takes for Bond to roll out his plane, there would never be enough street left for him to get airborne.
Continuity mistake: At the beginning of the film, Bond takes off with his plane. When he is about to take off you can see the wheels under the plane, but in the next shot the wheels are gone.
Continuity mistake: During the fight on the roof of the train, the scenery in the background changes dramatically between shots. Especially when the surviving knife artist climbs up on the roof. There we are in a dense forest, and when we cut to Bond, we are on an open field.
Other mistake: When Bond kicks the curry onto the hot coals, the flames flare up very high over the length of the coals, and not just where the curry hits.
Factual error: Udaipur where the floating palace is located is 350km from Agra, so Bond wouldn't be passing Taj Mahal upon landing in the helicopter.
Answer: Bond (taking over for the Major) had 1 piece on point 2, 1 piece on point 3, and 2 pieces on point 6. Rolling doubles in Backgammon means you get to make 4 moves instead of just 2, so he was able to remove all 4 pieces. If you have a piece on point 2, you don't have to roll a 2 to remove it. Anything higher than a 2 can be used to remove the piece. Kahn even says Bond has to roll a double 6 in order to win, which he does.
