Tons of new Avengers: Age of Ultron pics are in from Johannesburg! A lot of them are from different sources, so this took a lot of work. They don't seem to be to high-security for these scenes, as it seems just about anyone sneaky can make it on set.
The most peculiar thing is that they put snow in Johannesburg. Why would you add snow to an African city? Or is it ash and soot from some crazy disaster? Either way, the fog that surrounds the scene looks just like what snow makers look like. I would know too, me and my dad built one just for kicks and we use it every Winter. I know, it's an unusual hobby.
