Steven Moffat, the new producer of the series, said Smith was perfect casting because he was someone who was old and young at the same time. "The Doctor is a very special part, and it takes a very special actor to play him. You need to be old and young at the same time, a boffin and an action hero, a cheeky schoolboy and the wise old man of the universe. As soon as Matt walked through the door, and blew us away with a bold and brand new take on the Time Lord, we knew we had our man."
Of his casting, Smith said: "I'm flabbergasted. I haven't slept really! [Doctor Who] is an iconic part of our culture, and now I'm taking that on. It's nerve wracking. Exciting. Exciting."
