In total, there have been seven different James Bonds to grace movie screens, each a little different than the last. In order to explain these different Bonds, one theory postulates that James Bond 007 is actually just an alias that has been used by several different British agents over the years. This would explain how one man has managed to stay superbly youthful since his first appearance in 1962. Moreover, we’re led to believe that Daniel Craig’s Bond films are reboots, but Judi Dench still plays M, like she did in Golden Eye in 1995. So theoretically, it’s the same universe with just a different Bond.
