The first images of Aaron Taylor-Johnson and Elizabeth Olsen on-set and in-costume have been papped.
And not only that, but the appearance of a shiny robot-like figure means that we could be getting our first glimpse at the Avengers sequel's Big Bad Ultron.
As for the brother-and-sister bad-ass double act, they're looking pretty faithful to the
concept art that was revealed by Marvel
, with Olsen rocking a grunge-y look for her role as Scarlet Witch, and Taylor-Johnson sporting a skin-tight aerodynamic blue suit for his super-zippy turn as Quicksilver.
And as for that robot? Well, that's anyone's guess.
It's also heartening to see a few shots of Jeremy Renner's Hawkeye mixing it up with the pair, as the comic backstory involves those three becoming four of the new members of the Avengers after three of the founding members left.
But what do you think about the costumes? Let us know in the comments below!
