Some snaps from this week's rehearsals

The ice and snow have finally gone from Dunsfold, which meant premium conditions this week for our latest guest: the time-travelling Doctor himself, Matt Smith.

And among the dignitaries Joining Matt down at the studio this week were a very fast Mercedes, a very fast Maserati, some sadly discontinued Saabs, and three presenters in slightly less bulky winter jackets.

Click on for some more snaps of the week's rehearsals, and we'll see you all on Sunday at the usual time: 8pm, BBC Two and BBC HD.
