Continuity mistake: At one point, during the scene with the helicopter dogfight, the tail wing of Bond's mini-copter is riddled with bullet holes (and yet the mini-copter continues to fly very efficiently), but for the rest of the scene, the tail wing is in perfect condition with no sign of the damage done to it. (00:56:40 - 00:58:45)
Factual error: When M and his entourage arrive at Bond's estate their cars are surrounded by sheep. They then drive on down a unsurfaced road to Bond's house, past a pride of lions he keeps on the grounds. A series of sweeping overhead shots shows us it is all one huge field, with no fences or the like. Those sheep aren't going to last very long.
