These 501st'ers took a trip to the set locations of Hoth, maybe they have photography which could be useful as background plates.
I'm already looking into it. One of them approached me a while ago concerning footage. =) For now he wishes to remain safely anonymous...
Ady has also received other images for backgrounds from another source from Finse as well or so I've heard.
