Are we getting a glimpse of the titular villain from Joss Whedon's Avengers: Age of Ultron via AostaSera.it?
While there's no way to be sure this is Ultron, as of now there's no reason to discount the possibility that this is a stand in for the villain. That would certainly change the assumption under which most of us were operating, but after today's set pics, I've been beginning to think that this scene is not from the beginning of the film. I think with Scarlet Witch and Quicksilver looking "geared up" instead of like prisoners, this takes place after they've joined the Avengers. It's also very possible that the other mo-capped guys are Ultron clones from the Quicksilver concept art.
And we do know for sure that this is a picture of Joss Whedon on set!
And this extremely clear look at Ultron from @nailbiter111:
