The new James Bond film will be "Bond with a capital B", according to its star Daniel Craig.
Veteran actor Albert Finney joins Ralph Fiennes and Javier Bardem in the cast for the film, which is called Skyfall. They will join regulars including Dame Judi Dench, who plays spy boss M, in the film directed by Sam Mendes.
Producer Michael G Wilson said the title - officially confirmed at a press conference - was "the worst-kept secret in London".
Mendes, who admitted he had been a fan of the films since childhood, said the film would be shot in locations including London, Turkey and Scotland.
Craig, who has already starred in two films as the suave secret agent, said he would like to play 007 for "a few more years".
He said: "Being lucky enough to get the chance to do a third one, it is my intention to make the best Bond movie we possibly could - and Bond with a capital B - and I'm just incredibly proud to be part of this group of people."
The Bond girls are played by Naomie Harris, who plays an agent called Eve, and French actress Berenice Marlohe who said her character would be "glamorous" and "enigmatic".
Harris revealed she has been in training for the role, saying: "I've been doing yoga three times a week to get into shape and stunt-driving and firing machine guns, which I've discovered I've got a real taste for."
Producer Barbara Broccoli said they had been "considering various people" to perform the film's theme music but had not made any decision.
The announcement of the new film comes 50 years to the day after Sean Connery was announced in the press as the man to play the superspy in Dr No.
