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 - chronological order
Directed by: John Glen
Starring: Desmond Llewelyn, Timothy Dalton, Robert Davi, Talisa Soto, Carey Lowell
Factual error: The discharge from an electric eel doesn't make flashes of light or sparks in the water, as shown in this film. (00:30:00)
Felix Leiter: Where's my wife?
Dario: Don't worry. We gave her a nice Honeymooooon.
Trivia: This was Timothy Dalton's second and last appearance as James Bond. He initially agreed to play Bond for a third time in "GoldenEye" (1995), but resigned from the role in 1994, believing that too much time had passed since "Licence to Kill".
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.
