Smith, who recently shaved his head for his role in the upcoming Ryan Gosling film 'How To Catch A Monster' spoke to ITV's Daybreak at last night's GQ Awards, where he also explained he will have to wear a wig once filming commences.
"I [cut my hair] for a film, but it means I have to wear a wig in Doctor Who, which is a nightmare.
"I'm excited - I start shooting the Christmas special [on] Sunday. It'll be sad - the end of a wonderful era!"Doctor Who will return to TV screens for Smith's penultimate adventure as the Doctor, in the show's 50th Anniversary special on November 23rd.
