Plot hole: In the pre title sequence James Bond travels in a hovercraft along the dirt road which is full of land mines. Soon after reaching the waterfall at the end, trucks drive up along the road he just drove in on to capture him. As there was only one road in to the waterfall complex the landmines must have all disappeared, as earlier on in that sequence we are informed that the only way that the North Koreans can avoid the mines along that road is by hovercraft.
Continuity mistake: When Jinx and Bond sneak onto Grave's plane, Jinx can be seen with a nickel plated pistol (this is also evident throughout the entire film). Yet when Jinx is in the cockpit and Frost tells her to hand over the gun, it's now no longer nickel plated but standard gun metal black.
