Possible spoilers follow:
Shooting has been taking place at the Margam Country Park, with both Matt Smith and Jenna-Louise Coleman on set. The story appears to be a historical, possibly Victorian-era.
The possibel name for the new companion is Clara
Here’s the first decent quality look at Clara alongside the Doctor. The Doctor has had a bit of a wardrobe change, wearing a brown jacket with waistcoat underneath.
