Title Roles in Bond Films

I'm sorry, but there was no title role in Live and Let Die.

The best answer to this question, I would suggest, is The Spy Who Loved Me. I reckon this is the only time James Bond has been the title character in a Bond film.

There aren't actually that many people who have played the title roles in Bond films. I would say Joseph Wiseman in Dr. No, Gert Frober in Goldfinger, Christopher Lee in The Man with the Golden Gun, and Maud Adams in Octopussy. That's five, including Roger Moore.
