David Tennant

At a young age, David Tennant was already set on becoming an actor – he was just three years old at this point. Now, what is the reason behind this goal, you ask? Well, as it turns out, that credit goes to the sci-fi TV series Doctor Who. With that said, Tennant began his journey into the acting scene not long after, when he was still in secondary school.

Like a severe case of things going full circle, Tennant has since become universally known for portraying the tenth iteration of the titular Doctor in the Doctor Who series. Besides his tenure in the world-famous sci-fi program, the actor was also able to showcase his acting chops in other projects. Some notable titles include Harry Potter and the Goblet of Fire, Jessica Jones, and Hamlet. Plus, besides his performance in movies, shows, and stage plays, Tennant also displayed a knack for voice-acting, lending his voice to shows such as DuckTales and the upcoming series, The Legend of Vox Machina.
