Ascended Fanon: Bond coming from a huge manor is a third-party addition from the novels.
Banned in China: It is actually censored for a scene where Bond himself kills a Chinese security guard and for the parts where Severine mentions of being a child prostitute in Macau.
Development Hell: Production stalled for a while as MGM went bankrupt and Eon decided to wait until the studio got back on their feet... The entire creative team agrees that the delay gave them the time to fine tune the script. Plus, the eventual release date ended up coinciding with the franchise's 50th anniversary.
Easter Egg: If you pay close attention to the title sequence, Silva's torture is in there too, right after the Chinese dragons. Notably, it's fire themed, as opposed to Bond's parts, which started with a water theme.
Sean Connery was the director's first choice to play Kincade, but he ultimately wasn't approached for fear that it would take the viewers out of the movie.
Some of Kincaid's lines suddenly take a whole new meaning when one realises Connery was envisioned for the role. Especially the one where Bond asks him if he's ready, and Kincaid replies "I was ready before you were born". Daniel Craig was indeed born 6 years after 1962's "Dr. No".
Director Sam Mendes has stated he originally planned to open the film with the Bond Gun Barrel sequence, but realized it would have conflicted with the shot of Bond walking into focus in the first scene.
