Behind-The-Scenes Pics From "Doctor Who"

Now when I first saw these pictures I thought, "Why is The Doctor outside the Ponds house?" because I thought Karen Gillan and Arthur Darvill already wrapped with filming a few weeks back.
The other thing is what the hell is in that black box and why are U.N.I.T there too. Either someones in BIG trouble with U.N.I.T or something bad is going to happen to The Doctor and the Ponds.
