Eva Green as Vesper Lynd from Casino Royale (2006)

Vesper Lynd is a fictional character featured in Ian Fleming's 1953 James Bond novel Casino Royale. She was portrayed by Ursula Andress in the 1967 James Bond parody, which is only slightly based on the novel, and by Eva Green in the 2006 film adaptation.

In the novel, the character explains that she was born "on a very stormy evening", and that her parents named her "Vesper", Latin for "evening". Fleming created a cocktail recipe in the novel that Bond names after her. The "Vesper martini" became very popular after the novel's publication, and gave rise to the famous "shaken, not stirred" catchphrase immortalised in the Bond films. The actual name for the drink (as well as its complete recipe) was mentioned on screen for the first time in the 2006 film adaptation of Casino Royale.

In 1993, journalist Donald McCormick claimed that Fleming based Vesper on the real life of Polish agent Krystyna Skarbek, who was working for Special Operations Executive.
