David Tennant popped onto the radar of most of his fans when he appeared as the tenth Doctor on "Doctor Who," but his career doesn't begin there. The actor got his start in the theater, a medium to which he frequently returns, playing leading roles in Shakespeare plays for major companies and venues across the UK. Tennant's immersion in the world of show business created ties that run deep: he is married to Georgia Moffett, the actress who played the sort-of-clone of the Doctor in "The Doctor's Daughter," who is herself the daughter of actor Peter Davison, another actor who once played the Doctor.

David Tennant somehow makes every character he plays likable and relatable, even when they're one of the baddies. His instant rapport with audiences makes his appearances memorable, and the characters he has played become instant favourites in their respective franchises.

While he has found tremendous success on the stage and in television, David Tennant hasn't had a breakthrough role in a feature film. This may be a product of his "type" of actor; Tennant isn't bland enough to play generic heroes or villains, or perhaps the kinds of stories made into films just aren't geared toward his audience or his awesome arsenal of acting skills. Still, we can all see ourselves as one of his roles. Which one do you think you are?
