Matt Smith took over the role of Doctor Who from David Tennant in 2010, making him one of the youngest Time lords in the history of the show at 30 years old.
This past weekend, BBC reported that Smith will be leaving Doctor Who and his final appearance will be in the Christmas special, at which point a new Time Lord would be introduced.
There is already speculation about who could take over from Smith, and one name that's prominent in reports is John hurt. Mr. Hurt is known for many blockbuster films, including The Elephant Man and the Alien films, and has actually been nominated for an Oscar twice. There is a lot of fan support for him to get the role, but Hurt himself remains coy when asked about the role. When asked about it, Hurt simply says, "I have absolutely no idea who the new Dr Who is.”
It's rumored that several other actors are also in contention, including Homeland actor David Harewood, Roy Kinnear, and Downton Abbey's Dan Stevens. Right now, it really looks like John Hurt will be the one chosen for the role, but we never know. We'll have to wait until the Christmas special airs to find out.
