I've never been able to get into Doctor Who, but I loves me some David Tennant. His performances in Broadchurch (Not that crappy American Gracepoint remake nonsense, mind you), Jessica Jones and, most recently, Good Omens, have been absolutely amazing. There's something about him that draws the eye and makes you believe in what he's selling on-screen. He doesn't oversell his characters and its rare to see him steal authority from those working a scene with him. His craft's earned him a huge amount of celebrity in recent years--a fact that he hasn't always been comfortable with.
In this candid interview, Tennant talks about his having to come to terms with being 'public property,' and how celebrity can change one's life for both better and worse.
