Matt Smith, the 30-year-old, bow-tied 11th Doctor Who, will leave the iconic British sci-fi series after the 2013 Christmas special, setting "Who" fans on a guessing game to try to predict — and offer dream casting suggestions — who will replace the youngest Who ever.

Here are various names being bandied about as possible new Whos, as well as our take on the chances of them steering the TARDIS in the near future. — Kimberly Potts, Yahoo! TV
