Downton Abbey star Maggie Smith has said that she has never watched the period drama.

The 78-year-old star, who plays the part of Countess Violet Crawley on the show, has admitted that she has never tuned in to watch an episode of the hit drama.

Speaking on 60 Minutes, Smith said: ''I don't sit down and watch it. I haven't watched it.

''I will look at it when it's all over, maybe. Because it's frustrating - I always see things that I would like to do differently and think, 'Oh, why in the name of God did I do that?'''

Despite winning several awards for her role in Downton Abbey, Smith insists that she has no interest in fame, adding: ''I don't feel any different to the way I felt before, and I'm not quite sure what [being a star] means. I am familiar to people now, which is what I was not before. That is entirely due to the television set.''
