I never made this connection before, but director Sam Mendez of the next Bond movie (Skyfall) points out a remarkably obvious similarity in retrospect:
MENDEZ: Thatâ€™s why I mentioned the word in the press conference, â€œregenerationâ€ rather than â€œevolving,â€ because I feel it is like, you know, we have Doctor Whoâ€¦thereâ€™s a geek answerâ€¦we have Doctor Who and I was brought up on the idea of Doctor Who, who at the end of his final episode, he dissolves and a new actor pops up and he regenerates and itâ€™s a whole other character: sometimes itâ€™s an old man, sometimes itâ€™s a young man, but he just changes. Iâ€™ve always loved that idea.
The interesting thing here is that unlike other characters, both Bond and The Doctor are actually different in each regeneration. I mean, we’ve had multiple franchises for Batman, Spiderman, and Superman, but none of them really offer a really different take on their titular characters. Bond actually changes quite a bit between incarnations, with Moore being more reserved, Connery being more charming, and Craig being more conflicted. Of course not as much as The Doctor, but the idea is interesting.
