The first official synopsis has been released for forthcoming James Bond movie Skyfall.

The eagerly anticipated movie - which will see Daniel Craig return in the role as the British spy - will place the relationship between the leading man and character M, played by Dame Judi Dench, under pressure.

"Daniel Craig is back as James Bond 007 in Skyfall, the 23rd adventure in the longest-running film franchise of all time. In Skyfall, Bond's loyalty to M (Judi Dench) is tested as her past comes back to haunt her. As MI6 comes under attack, 007 must track down and destroy the threat, no matter how personal the cost."

The movie - which stars newcomers to the series Ben Whishaw and Javier Bardem - is currently shooting in London and is due to be released in November 2012.

According to reports, Naomie Harris, who is set to play Miss Moneypenny in the new movie, was told she had to change her voice to play the role in a sexier manner. "She has to lower her voice on camera because she has a very high-pitched girly tone. Naomie needs to sound husky, sexy and more womanly," a source said.
