Matt Smith: 'I can't play the Doctor forever'
Matt Smith does not think she would be able to play the role of Doctor Who indefinitely because it has started to take a toll on him
Matt Smith doubts he'll be able to play a part in 'Doctor Who' for much longer.
The actor is about to appear in his third season of the hit BBC show and he has admitted the job - which sees him film for 12 to 14 hours every day for 10 months a year - has started to take its toll on him and he says he doesn't think he'll play the Doctor for many more years.
He said: "I don't think you can sustain it. Tom Barker [who previously played the Doctor] did it for seven years but he did it in different circumstances. I couldn't do this for seven years. I'd be run into the ground.
"And your life outside of it is ... I don't know. I hope I don't sound too pessimistic. It's just I don't think my body or my life or the people around me could sustain it."
The star has committed himself to the sci-fi drama until at least 2014 and he has also revealed his hopes to star in movies as well as directing.
However, he admits for now he's happy in his role as the Doctor as it allows him a lot of variety which makes it exciting.
Speaking about his character he told Empire magazine: "He constantly allows you to reinvent him. That's what's interesting about this year. It's about what a new companion reveals in him.
"It's like a Shakespearian tragedy, 'Doctor Who'. There's a theatre to it. Because every day you're either facing the end of the world, or the loss of the person you love the most, or the invasion of the most appalling creature or alien that you can ever imagine."
