Continuity mistake: On the cable car, Jaws punches Lois, who knocks her head against an iron structure. A frame later, when the angle changes, she is knocking her head again.
Revealing mistake: When Bond is freefalling, the stunt man's jacket has a very obvious zipper on the back, to allow the safety parachute underneath to open in case of emergency.
Continuity mistake: When the movie starts and Bond is in the plane, the champagne bottle faces a 9 o'clock or 11 o'clock position, depending on the shot.
Continuity mistake: During the parachute scene, Jaws has green goggles, but his stuntman in the wide shots wears transparent goggles.
Revealing mistake: During the parachute scene, in the wide angles Jaws' stuntman has perfect straight white teeth, nothing like the characteristic edgy metal teeth.
Continuity mistake: When the space station laser deploys, the American space shuttle can be seen in the distance, with the curve of the Earth angled next to the shuttle. The shot changes to a close-up of the shuttle, and the curve of the Earth is now directly underneath it.
Revealing mistake: When Jaws goes to pull the ladder with the man on it, we see a close-up of him (with short hair) in shock then it cuts to a doll (with curly hair) falling back with the ladder. (01:48:40)
Revealing mistake: When Bond stops to study the map at the beginning of the Amazon chase sequence, you can catch some brief glimpses of a black object floating in the water. This is actually the explosive charge used to simulate the initial mortar fire's impacts from his adversaries' boats. Keep a close eye on those 'shell impact' locations to spot them proper.
Revealing mistake: In many of the scenes which are supposed to be taking place in zero gravity, the womens' hair still falls in the normal way instead of floating.
Continuity mistake: Shortly before Drax farewells James Bond in the Brazilian base, the countdown on the screen says "T -00:14:06". Six seconds later, it's "T - 00:11:08". Another five seconds later and the "T-" is gone. Looks like they cut a bit or two there. (01:25:45)
Other mistake: In the boat chase on the Tapirape, Bond's torpedo hits the enemy boat either on its back or left side, but neither are damaged by the explosion in a subsequent shot. (01:18:15)
Factual error: When Bond and Goodhead's space shuttle enters space, it still has the main fuel tank attached. However, when Bond releases the fuel tank it falls downward. It should maintain its momentum in orbit around the Earth until atmospheric drag (which extends out to high orbit) causes the orbit to decay over many years.
Continuity mistake: In Venice, the man in the coffin throws a knife at the captain of the gondola and one at Bond. There were 4 knives besides him and 3 after that. When he dies, the knives have disappeared.
Revealing mistake: When the pods are launched from the space station, it's obvious that they are models mounted on threads.
Visible crew/equipment: When Bond is fighting in the sky with the pilot, there's some shots where the shadow of the cameraman passes over them.
Continuity mistake: The helicopter on which Corinne Dufour and James Bond fly has a huge number written on the bottom, but it has disappeared when they arrive at Drax's palace.
Factual error: When James Bond is in the control room of the secret base, I think it's when the second shuttle takes off, there's the time at the bottom of the TV screen moving forward, but it's written T- instead of T+.
Audio problem: When Bond is being shot at while motor-boating away from his pursuers in Venice, at one point during the chase, they shoot right next to a rope on his boat and a sound from a silenced handgun is heard when the bullet hits the wood. No one is using a silenced handgun.
Continuity mistake: When the bad guy is struggling with Bond at the beginning trying to get the parachute, just before Bond kicks the bad guy away for good, there are shots of Bond's face and he's wearing the kind of eye protection goggles Jaws has on, only in a clear color. Bond didn't have these with him and never put any on, and in shots after the bad guy gets the boot, he doesn't have the goggles on anymore.
Factual error: There are way more Marines in the American shuttle than it should be able to hold.
Answer: They would die or escape and go feral, as would zoo animals, farm animals etc.
