Matt Smith has no plans to quit 'Doctor Who'.

The 30-year-old actor has played the Time Lord for three years and says he is very happy on the BBC One sci-fi show and is looking forward to the next 12 months.

He said: "We've got Doctor Who's 50th anniversary coming up in November 2013, and one assumes there'll be another Christmas special after that, and I'd hope to be part of it. I take each year as it comes. All good things come to an end, but my mum is aghast at the thought of me ever not being the Doctor. The show is the star and will continue without me.

"I'm committed to it next year and will sit down with Steven Moffat and see where we go from there. I've no immediate plans to leave. I'm around for a whole year and that's a long time."

The Doctor was recently joined by a new assistant called Clara and Jenna-Louse Coleman, who plays her, says being on the set is like "magic".

She told Radio Times magazine: "Every day has been surprising. You walk into the studio every few weeks and whole new sets have been built. You open the TARDIS doors and you're suddenly in a different era. It's very technical but also fun and adventurous, and it's OK to run down a corridor shouting and being silly and ridiculous as you like. It makes me feel like a big kid. It's like magic."
