Factual error: In the scene where Zukovsky is almost drowning in caviar he lies very deep - only the top of his face above the surface. The depth of a body in a liquid depends on the proportions between the density of the body and the liquid. For example in the Dead Sea, with its high salt content, the water has a high density, so a body floats higher than in fresh water. Caviar must have a quite high density too - probably as high as the water in the Dead Sea, since it tastes quite salt too. So if a person was floating in caviar, he would not go as deep down as Zukovsky does in that scene. That looks more like how deep he would go in fresh water.
Factual error: When the pipeline explodes it is clear during the explosion that it is mostly fire coming from the pipeline. There is no spray of earth or other debris. But afterwards Bond and Christmas are walking through a huge crater. Where (and when) did the earth get displaced, if it was not thrown up in the actual explosion?
