Jenna-Louise will get a new companion to travel through time in the sci-fi series

Matt Smith is quitting Doctor Who after 4 years travelling through time with his sonic screwdriver.

When you gotta go, you’ve gotta go,’ says Matt, 30.

Doctor Who has been the most brilliant experience for me as an actor and a bloke, and that largely is down to the cast, crew and fans.

The fans are unlike any other; they dress up, shout louder, know more about the history of the show – and speculate more about the future of the show – in a way that I have never seen before, [their] dedication is truly remarkable.’

Jenna-Louise Coleman, who plays Doctor Who‘s cute assistant Clara Oswald, will not be leaving and has signed for 2014. 

The former Emmerdale star is hoping she will have the same rapport with whoever replaces Matt.

I felt a bit of the chemistry from the very first audition we did together,’ Jenna-Louise, 26, tells TV Magazine.

I actually walked away feeling like I’d been knocked off my feet. It was a bit of a hurricane.

What was lovely was that Matt made me feel like he was auditioning with me – it was like show and tell.

The producers left the room so me and Matt could run around and play. I was really thrilled and excited.

He really makes me laugh as the Doctor.

Matt’s constantly exploring things to play with – which makes him a brilliant Doctor – but when you’re the person who’s trying to keep a straight face, it’s very hard.’

Matt has now started filming How To Catch A Monster, directed by Ryan Gosling,
but will appear in the 50th anniversary Doctor Who special in November and the
Christmas Day show.
