James Bond's original drink was:
"Three measures of Gordon's, one of vodka, half a measure of Kina Lillet. Shake it very well until it's ice-cold, then add a large thin slice of lemon-peel"
A traditional martini wouldn't have any vodka, although I'm not sure how much vermouth you should be putting in there. Kina Lillett was apparently quite strongly flavoured (quinine?) so you'd only need a little. I think it's since changed names/labels/recipes, and the taste is more user-friendly?
Shaking it probably helps make the vermouth more manageable, as well as getting it colder (if you can palate a mix like that without chilling, you're probably used to drinking cheap vodka from the bottle, on street corners
James Bond usually drinks larger quantities of more exotic things in the books, whereas it's all toned down a bit in the films. I think he got a whole case of Bollinger RD
on room service in "License to Kill" though!
