Plot hole: Bond goes after Lupe after she leaves the casino table, and they have quite a lengthy, hush-hush conversation. It's a casino, and there are cameras everywhere. Certainly, this would have been brought to Sanchez's attention since he was already leery of Bond and possibly Lupe.
Licence to Kill (1989)
1 plot hole
Directed by: John Glen
Starring: Desmond Llewelyn, Timothy Dalton, Robert Davi, Talisa Soto, Carey Lowell
Continuity mistake: In the scene on the plane, you see Bond hanging at the door on the right side of the plane. In the next shot, you see the plane making a left turn. In the following shot, Bond is still hanging on the right-side door. Shouldn't he have fallen into the plane?
Felix Leiter: Where's my wife?
Dario: Don't worry. We gave her a nice Honeymooooon.
Trivia: When Sanchez is chasing Bond in the trucks, and when he starts to shoot Bond with the Uzi, listen to the ricochet off the bullets. They sound like the James Bond theme tune.
More questions & answers from Licence to Kill
Chosen answer: "License to Kill" is partly based on the novel "Live and Let Die" and the short story "Hilderbrand Rarity". However, it is the first Bond film not titled after a book. While "The Spy Who Loved Me" shares its name with a book, it was the first Bond film not based on a book (though subsequently, there was a novelization of the film.) "Goldeneye" is the first film not based on a book AND not titled after a book.
