So today we got our first pics of Jeremy Renner on set. There are a bunch, some more spoilery than others, so here are a few to get you started, and then I'm going to link more.

(P.S. It's a little hard to tell what's legit and what's not, but it seems like call sheets suggest Natasha is also in this sequence, although Scarlett is still on the press tour for another week.)







(source -- WARNING link also has pics of Scarlet Witch, Quicksilver, and what I think is a mo'cap Ultron, so click at your own discretion)

More pics of just Renner/Clint at this tumblr

And a video (also contains Scarlet Witch):
