Well it may be official, then again maybe it's bullshit, but according to Daniel Craig, there won't be any continuation on the Quantum storyline. Craig had this to say.
The next James Bond movie won't be a continuation of "Quantum of Solace" or so claimed two-time Bond depicter, Daniel Craig. Addressing the future of James Bond movie, Craig slammed down the speculation that "Bond 23" would be part of a trilogy. "No f--king way," he said to Collider at "Defiance" press day. "I'm done with that story. I want to lie on a beach for the first half an hour of the next movie drinking a cocktail."
Explaining further, the 40-year-old actor insisted, "We've finished this story as far as I'm concerned. We've got a great set of bad guys. There is an organization that we can use whenever we want to. The relationship between Bond and M is secure and Felix is secure." He then added on where he would like to see the franchise is moving on, stating, "Let's try and find where Moneypenny came from and where Q comes from. Let's do all that and have some fun with it."
No, I wasn't a fan of "Quantum of Solace." You can't make a movie as awesome as Casino Royale then follow it up with something utterly retarded. But it kept my attention. When I left the the theatre I wanted to know what would happen with Quantum. I wanted to know what it was, who was running it, everything. But now you're going to leave it unfinished. Poor choice of words Craig, poor choice of words.
