Avengers: Age of Ultron is currently filming out in the open in Italy, and so unofficial videos and images are leaking out.  In addition to providing a look at Scarlet Witch (Elizabeth Olsen), Quicksilver (Aaron Taylor-Johnson), and Hawkeye (Jeremy Renner), the scene shows people fleeing in terror, which includes explosions and the requisite appearances of "Man with Briefcase" and "Woman Holding Baby".  There's also a metal humanoid, who is presumably the villain Ultron (James Spader) since you can see in one of the set photos they're trying to cover him up with a black cloak in order to hide him until they're ready for a proper unveiling.  Since these photos have leaked, that attempt isn't going so well.  I'm also a little surprised there's a practical Ultron on set since I assumed the entire character would be done entirely with motion capture and CGI.  [Update: Check out higher quality photos here.]

Hit the jump to check out the images and video.  The film also stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Paul Bettany, and Mark RuffaloAvengers: Age of Ultron opens May 1, 2015.
