It is said, that Ian Flemming designed this drink himself, with the help of bartenders at Dukes hotel in London. He apparently was fairly proud of it, but unfortunately it never shows up again. In the movies Bond tends toward straight vodka more often than not. Fortunately, Casino Royale was finally made into a full-fledge Bond movie, and in it this drink is once again introduced to the public. The new movie is intended to take place in the modern day, but James still orders his drink using “Kina Lillet”, this either shows that the scriptwriters didn’t really do any research on the product at all, or were intent on preserving the dialog from the book while sacrificing accuracy.
