Revealing mistake: When the shuttle ejects the engines you can see the support wires used to pull off the boosters.
Revealing mistake: During the boat chase with Jaws the close up of Bond driving the boat reveals at the bottom of the screen part of the camera rig holding the camera in place. In other long shots these brackets are missing from the boat.
Revealing mistake: During the shooting in the space station, Holly and another guy jump in a ditch and start shooting at the baddies. Seconds later the same shot is repeated. (01:53:15)
Revealing mistake: When Bond is underwater struggling with a python he is replaced by an obvious stuntman. (01:23:15)
Continuity mistake: When Bond's gondola goes under a bridge an encounters the hearse, the canal they're in changes completely. The street on the right disappears and is replaced by a brick wall.
Continuity mistake: When Bond arrives to Venice he grabs a card from Venini Glass. From the immediate opposite angle the cards is gone.
Visible crew/equipment: After Bond/Roger Moore's stuntman throws the pilot out of the plane, a safety bar connecting the plane and the stuntman's body is noticeable.
Visible crew/equipment: When the pilot aims a gun at Bond, there's a black bulky object reflected (filming crew or equipment) on the ice cube which disappears in the opposite shot.
Continuity mistake: Before Bond jumps out of the boat with the delta wing glider, the sky swaps from sunny to cloudy and back to sunny, between shots.
Continuity mistake: After Bond and Goodhead jump on the grass and he says "for saving my life" her arm swaps from being around his nape to by her side.
Revealing mistake: During the cable car scene, when Bond and Goodhead are sliding down, not only is the image in the background a still image (check the boat left of the island, and the waves next to the coast on the right), but the very same shot of them sliding downwards is used twice.
Factual error: The station's gravity is turned on and off several times before and during the battle. The film establishes the gravity is on because the station is rotating. Bond and Holly turn off the gravity to prevent the Americans from being shot down. Then, after the American Marine shuttle docks, gravity is restored and is never seen being deactivated again. However, the station begins to take on serious damage from the battle and literally begins falling apart. Even setting aside the fact that the mass shifts would affect the station's ability to produce gravity, the external shots of the damaged station don't indicate it's even rotating anymore, but everyone inside is still able to move around as if gravity is still active up to the final destruction of the station.
Continuity mistake: When Bond is in the speed boat he puts a white helmet on, cut to the front of the boat when the wings are deployed and the helmet is missing, then the long shot of the hand glider and the helmet is back, Bond is also dry despite getting soaking wet by the explosions.
Other mistake: When the shuttles dock we see a close up of one docking, on the side of the shuttle is the hatch which completely misses the docking arm but we hear the sound of it making contact.
Revealing mistake: During the boat chase in the jungle, in several of the front shots of Bond's boat you can see the wake from the camera boat in front of him.
Visible crew/equipment: During the speed boat chase you can see the charges floating in the water - they are black squares/rectangular.
Revealing mistake: During the speed boat chase Jaws waves the 2nd boat past. The boat goes from right to left and the camera boat goes left to right - in the background you can see the wake from the camera boat. It's doing a 360 degree turn, completely different to the one Jaws is on.
Revealing mistake: During the boat chase in the Amazon the second boat blows up twice and is moving very fast but the third explosion shows the boat stationary with no time to stop.
Continuity mistake: When Bond and Goodhead are in the back of the ambulance the interior does not match the outside - the windows are a different shape and the roof is too high.
Revealing mistake: When Moonraker 6 jettisons its small fuel pods, the one on the right has a visible wire behind it.
