Well, it's official – the next James Bond movie is Quantum of Solace.
It's a Fleming title, from a short story in the Bond collection For Your Eyes Only, but it's also probably the least cinematic title in the Bond canon. The story isn't even really a James Bond adventure – all Bond does in it is listen to a man at a cocktail party tell a story about a couple's screwed-up relationship and then go back to his hotel. It's an interesting, atypical Fleming story that I've actually always liked, but it certainly doesn't seem to be movie material.
Still, it's an actual Fleming title, and it indicates that the producers are sticking with the back-to-basics approach of Casino Royale. Tanner, over at the awesome Double O Section blog, has a very thoughtful post about this title, the original Fleming short story, and what it may bode for the new film. He also has pix of the new Bond Girls™, if that interests you.
Quantum of Solace is filming now and is scheduled for a Christmas release.
