There were talks of doing a movie spinoff with Jinx, but this film's reception buried those plans very quickly. Apparently, the script for the first Jinx movie was surprisingly down-to-earth and even gritty, with a focus on Jinx's background of how she became an NSA agent. Even if the Jinx franchise was scrapped, this helped inspire EON to take a similar route with Bond for Casino Royale.
Originally, the main Bond girl was to be Gala Brand from Moonraker, and Jinx was going to be the mole (See why she's named Jinx?). This was turned on its head once Halle Berry got involved, though, with Jinx becoming the main Bond girl and Brand becoming the mole (and getting a name change to Miranda Frost, to avoid displeasing fans of the novel).
Wai Lin from Tomorrow Never Dies was set to return and give Bond a hand in Hong Kong. This fell through, and a new Chinese Intelligence character named Mr. Chang was written to fill her role.
