Never noticed this, will have to keep an eye out next time I watch (whenever that may be).
As an aside, I love Bond's line to Dent just before he shoots him. "That's a Smith and Wesson, and you've had your six". Awesome.
I love that moment too. At first you're thinking Bond is unaware of the obvious rug pulling, then you realize he knew it all along, and he went along with it. So simple and yet effective.
You know it deserves the GOTY.
