It's the second movie in the franchise restart. Think about it, "double" is in the title, 007 it will be ! That will make it the biggest tickets seller ever in the history of the franchise, the ultimate James Bond film !
Far from being a lazy title, 007 seems to me like an honour to be bestowed as a title on a worthy film. After all, a film worthy of the title 007 would have to be something pretty special, right?
Using 007 as the title would also mark BOND 22 out from all the other Bond flicks, which I imagine would please Forster, whom I suspect never signed on to direct "just another Bond movie".
And if they are going to use 007 as a film title, I don't see a more appropriate time than now.
If I had to guess, I'd say 007 is the most likely title, followed by THE PROPERTY OF A LADY. Still, who knows? Not me, that's for sure, so time will tell.
