Revealing mistake: During the laser battle inside the space station, one of the villains on one of the upper circular tiers makes a move as though to signify he was hit with a laser a second or two before the laser actually hits him.
Deliberate mistake: During the space battle, one of Drax's men gets his back pack blasted. (1:46:37) His entire pack explodes so that his jet pack and life support are destroyed. But as a result of that blast, all the parts from his suit FALL DOWN! Even though there's no gravity.
Plot hole: Near the end of the film Drax tells Bond he had his own shuttle hijacked because he needed it after another shuttle malfunctioned. OK then why didn't Drax just contact whoever he needed to before the Moonraker left on the 747 and have the working shuttle returned to his base before it left. He obviously had the time to get two of his people hidden in the shuttle so a few phone calls would have fixed his problem and the British government would have never had to involve Bond at all.
Factual error: Jaws cuts one of the steel ropes of the cable car by biting through it. Even with his metal teeth it would have been impossible for him to do that - to cut such a large steel rope would require hundreds of tons of pressure.
Continuity mistake: In the scene where Drax's assistant, Corine Dufor, is being pursued to her death by his doberman dogs, she starts off with bare legs and high heels, but a couple of seconds later she's now wearing trainers and blue socks.
Continuity mistake: The snake that attacks James Bond changes color during this scene.
Revealing mistake: During the skydiving scene, Jaws' stuntman is obviously different. Jaws appears to have a light skin complexion and be large in physique as normal but the stuntman has a tan skin color and is smaller in physique.
Character mistake: When James enters and exits the laboratory, the door has a sign on it that warns for radioactive materials. The laboratory actually contains a biological weapon. Therefore the door should be marked with a bio-hazard symbol. (00:41:00 - 00:42:00)
Continuity mistake: In Venice, a boat with a coffin passes Bond's gondola and when the coffin opens, the man has his left hand on his suit. In the next shot, he now has his hands joined together.
Continuity mistake: When the boat jettisons its roof, you can see the "folded glider" prop below being torn away with it towards the boat's left side. In the next shot it is centered again (of course) and unfolds properly. (01:16:05)
Continuity mistake: When the chopper arrives at the Drax estate, the clock on the facade shows it's 4:40. A second later, when it lands, it's 11:05.
Continuity mistake: Bond enters the Piazza San Marco with his gondola and a sailor watches him pass by. When the angle changes, Bond is meters behind, arriving towards the sailor again.
Continuity mistake: After the elaborate sequence showing each moonraker shuttle docking with the space station, a wide shot of the station shows two shuttles frozen in space not attached to anything. The most prominent is the shuttle in the top foreground. The shot looks like a still photo with the exception of the spinning radar dish at the bottom of the station.
Continuity mistake: Bond is in his boat being pursued by Jaws in another boat, and as they approach the raging waterfall, Bond activates the emergency hang-glider concealed within the roof of his boat. He flies away and there is no shot of his boat going over the falls, nor is his boat shown still in the water leading up to the falls when Jaws' boat approaches the falls. Jaws and his boat are shown going over the falls, but Bond's boat seems to have simply disappeared. [During filming of the scene Bond's boat got stuck on some rocks and never went over the waterfall as planned. The stuntman doing the handglider stunt would not do it again, so they had to make do with the film they had shot. They only had 3 boats to film the boat chase - one "hero" boat, one to film the hand glider scene, and a empty boat shell to go over the waterfall, which was damaged by the rocks. Still a mistake, but there's why.]
Revealing mistake: When Bond and Goodhead are in the Space Shuttle, when we see Goodhead reach for the pen her hair shows no effects of the lack of gravity.
Continuity mistake: Drax's henchman Chang's name changes to Chi during the film. (The DVD subtitles also call him Chang while the actors call him Chi).
Factual error: Drax hides his station by "jamming" Earth radar. However, jamming involves blasting out noise to confuse radar. At the very least, it would alert authorities that something was up there.
Revealing mistake: When James and Holly finally escape from the space station, there's a shot of it with debris falling towards Earth. They disappear when they pass in front of the Earth.
Plot hole: For the shuttle to land at Drax's Amazon hideout he would need a very long runway, something that could easily be detected by satellite.
Suggested correction: Why would they need to have their own runway? With everybody else dead, they could just pick from any existing landing sites. Also, it is not clear if they planned to use the shuttles for the initial return at all. Apparently, the pods at the end of the spokes are constructed with independent reentry capability, or else how would Bond's comment about the chances of Jaws and his girlfriend make any sense.
Suggested correction: No reason the Amazon crew couldn't construct one once the gas has dispersed, and everyone else on Earth is dead.
