UPDATE: FAKE, as reported by Metro UK and confirmed by Sony Pictures.
Original story: Looks like fans anxiously waiting for some footage of the next James Bond film starring Daniel Craig have an advanced teaser in their hands, as via the *fake* Sony Pictures YouTube page (and posted via Comic Book.com) has released a mysterious "Come and Dive" video that shows 007 walking into a memorial grave, with a mysterious woman's back seen and then fading to another scene which sees a beach.
Then the words "October 2015" come out, which is the official release date of the new sequel, the 24th Bond film that will be once again directed by Skyfall director Sam Mendes.
You can check out the video and see for yourself, which is truly an "official tease" if any.
No official word or description of the plot for "Bond 24" has been released as of this time. For more info on the *fake* teaser, visit the*fake* Facebook page of the movie.
