Re: Star Wars Episode 7 - 2015
Casino Royale was a reboot. Doesn't matter if the same actors are in the same roles, it was a new story and new beginning for the Bond franchise. M wasn't a woman in the original Bond movies. Judi Dench is just a very good M and I could see why they would want to keep her in that role.
