Doctor Who is currently shooting two episodes in Utah to transmit next year, and it seems that spies at Doctor Who TV have been able to get some photos and footage.
You can read their entire report at their website, which even includes some purported dialogue.
In the episode, Mark Sheppard (Supernatural, Battlestar Galactica) plays the interestingly-named Canton Everett Delaware III opposite Alex Kingston’s River Song. It is said that the next series of episodes will explore the character of River Song more, including the revelation of her true identity.

Here’s some video footage from “Timeboyy,” that you can enjoy for now until the BBC inevitably will have it removed:
And here are those pictures:
