Other mistake: In the casino scene they're playing Baccarat. Bunky reveals a natural 8 (5 and 3). When Bond's hand is revealed, the croupier announces 9 for the win: "et neuf la banque" ("and 9 for the bank"). Only, Bond has revealed a Queen and a 5 (a natural 5).
Other mistake: When Bond is being chased on the bobsled track, just before he escapes the track.there is a shot of Eric Kriegler taking one last shot at him. In this shot however, Kriegler's bike appears to be in an open area and certainly not on a bobsled track. In fact it looks like a disused shot from when the chase started.
Other mistake: General Gogol's helicopter has Polish civilian markings, SP-(3 letters), repainted so they would resemble Soviet ones. However, Soviet markings were CCCP-(5 digits). When Gogol comes out of the helicopter, the manufacturer's logo (PZL-&346;widnik) is visible over his shoulder.
Other mistake: During the car chase, Bond brakes hard and the two chasing cars crash into each other. The 2cv carries on with no problems. Bond only presses the brake pedal, which would cause the car to stall as he didn't press the clutch pedal at the same time, which you should do when driving a manual car.
Chosen answer: Whether he talked to her or not, Bibi would have inside information simply by being around him so much. She would have overheard things that a background check wouldn't reveal, like planned criminal activity.
