Italian website AostaSera.It has posted a number of unofficial photos from the Italian shoot of Joss Whedon's "Avengers: Age of Ultron," and in addition to some candid early photos of Jeremy Renner as Hawkeye and Aaron Taylor-Johnson as Quicksilver, there are also stills of what may be the first glimpse at Ultron -- though the photos aren't of high quality, and the identity of the character isn't completely clear. While James Spader was cast as Ultron in the upcoming "Avengers" sequel, there's no way to confirm it might be him in the metal suit. In fact, there's really no way of confirming that this is indeed Ultron, other than the obvious metallic resemblance.

Check out the photos below and judge for yourself.
