Current Doctor Who Matt Smith was a guest of presenter Colin Murray on BBC 5Live last night. His time on the show mainly consisted of "football" chat but included in the player above is the portion where Smith talked about Doctor Who. There is some discussion of the Christmas Special (lots of snow and crackers) whilst he states that filming on the next series begins in January.
Be warned, this clip also includes Pat Nevin.
