In 2008, with the news that David Tennant would be stepping down as the Doctor, many a name was bandied around as the next in line to take on the role. Amidst the speculation came rumor that Catherine Zeta-Jones was to become the eleventh Doctor. And given that former show-runner Russell T. Davies had at the time expressed his support for the casting, it seemed to be as good as done. Though these obviously proved to be untrue, I think she would definitely make an excellent twelfth. Zeta-Jones has an inner intensity that would add an explosive touch to the Doctors personality. You get the sense that she is someone you dont want to cross, someone who, while generally good-natured, can switch to vindictive and wrathful the second you get on her bad side. In short, she reminds me of David Tennant, which is never a bad thing.
