One other thing I forgot to mention, the night sequence where they sneak onto Crab Key was shot during the day and they put a filter over it. Pretty jarring to look at the characters who are all squinting because of the sun when it's supposed to be nighttime.
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.
