Scootyboy has put up a plethora of filming pics from Doctor Who's season 5 on his photobucket account. Go here to view them all. The pics date from January 6th 2010 so today!
It appears they are filming the Van Gogh episode. We see actor Tony Curran, who plays the artist, in many of the pics.
Seems like the Master Painter will get a trip in the Tardis!!
