Other mistake: The opening scene is at a military airbase which is hosting an equestrian event near the hanger that Bond blows up, and what an explosion that is, but all the civilians are more interested looking at Bond flying off instead of reacting to the massive explosion that just happened nearby.
Factual error: In the forest, Bond runs into a giant spider web. First, the spider's thread is far too thick and resistant. No cobweb could slow a person down. Second, there are several spiders hanging in the same web. Spiders don't share their nets with others. Third, these spiders are supposed to look like tarantulas, which don't spin webs. (00:59:30)
Revealing mistake: When Bond falls off the train the scenery switches from outdoor filming to an obvious film set.
Continuity mistake: When Bond is pinned to the wooden door by the knives we see each knife cut his shirt, trapping him to the door, but when he opens the door and grabs the knife with his left hand, his left arm is now completely free, with no holes or rips on his sleeve.
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.
