The links between Spectre and other films are:
Michael G. Wilson, who was a writer for Octopussy was a producer for Spectre.
Monica Bellucci, who is also in The Matrix Reloaded. Which I had completely forgotten. Both films should be on this list for sheer misuse of Monica Bellucci.
An interesting thing for me is who isn't credited for Octopussy, but are for Spectre. The two who interest me are Ian Fleming and Barbara Broccoli also not. It could be that Barbara Broccoli isn't credited because Octopussy was made before she began to help Cubby Broccoli with producing the Bond films. I don't have my Bond guidebook to hand (yes, I do have a Bond guidebook, I am a Bond nerd).
The other one is the lack of Ian Fleming. I wonder if it's because the new films try to push the "based on the books" thing more than the older films. Despite taking just as many liberties, because the books decided the "is Bond a sociopath?" question with a loud, cheerful, "yes he is and we love him for it." (Seriously, read the opening story in "For Your Eyes Only" peeps!).
