Millions of traditional James Bond fans will be shaken and stirred when their hero orders a 'Dirty' vodka Martini in his latest film, it emerged today.

'Spectre', which stars Daniel Craig, will see a dramatic break with the past as 007 shares a cocktail with French beauty Lea Seydoux, who plays a character called Madeleine Swann.

As they enjoy dinner together, Bond switches his preference from a Vesper Martini with a twist of lemon to a 'Dirty' - combining Belvedere vodka, dry vermouth, a muddled Sicilian green olive, and a measure of the olive's brine.

'You can see the olives in the glass,' said an insider on Spectre, which is released in Britain next month.

'Bond is clearly going for a Dirty Martini to impress his dining companion - it's all very sensual.

'Traditionalists might find it a bit strange, but the Dirty is in fact a great choice for a licensed killer who can't stop seducing women.'

The ambitious mix is certainly a departure from the far more clean-cut cocktail that Bond always ordered before.

Bond's exact words in Ian Fleming's book 'Dr No', which was published in 1958, were: 'I would like a medium vodka dry Martini - with a slice of lemon peel. Shaken and not stirred please. I would prefer Russian or Polish Vodka.'

Sean Connery sealed the myth in the 'Dr No' film four years later, when he was presented with a straightforward vodka Martini and lemon twist.

Connery's third appearance as Bond, in Goldfinger in 1964, then saw him use the now trademarked words 'shaken and not stirred' on screen for the first time.

The cocktail became the last word in bar room glamour, as thousands tried to emulate the British superspy by ordering one, sometimes using the world famous catchphrase.

Eyebrows were raised when, as part of a 28 million pounds advertising campaign, Daniel Craig was seen clutching a bottle of Heineken beer in Skyfall, the 2012 Bond movie, but there was also a casino scene involving a vodka Martini.

The superspy has always had a preference for Polish vodka, and Belvedere today confirmed it is sponsoring Spectre.

Speaking when the sponsorship was announced, Belvedere president Charles Gibb said: 'We are available in 120 countries around the world, and we know that in each of those countries there are millions of people eagerly awaiting the release of Spectre next November.

'I was in a bar in the middle of Delhi earlier this year and the bartender was quoting me endless lines out of Bond movies. So you get a massive amount of awareness that allows us to break into new markets.'

The specification for Bond's perfect vodka Martini are set out in the book Live and Let Die, when Solitaire pours him a drink, six parts vodka to one part vermouth.

According to Mr Gibb, you should stir for 90 seconds to get the right elements of dilution and chilling.
