Photos--Avengers 2: Scarlet Witch & Quicksilver In Action

Variety has our first on set look of both Wanda Maximoff, a.k.a. Scarlet Witch (Elizabeth Olsen) and her twin brother Quicksilver (Aaron Taylor-Johnson) from Joss Whedon's "The Avengers: Age of Ultron".

Production is underway at Bard Fortress in Italy--Renner's Hawkeye, Olsen and Taylor-Johnson are on hand for the filming which doubles as a snow-bound mercenary base in Eastern Europe.

The sequel DOES NOT follow the Age of Ultron comics storyline--in which the big bad Ultron was created by Hank Pym who becomes Ant-Man. James Spader will both voice Ultron, and he'll have to do some kind of motion-capture as well--This news puts to rest the most popular theory suggesting that Tony Stark's (Robert Downey Jr,) robot butler J.A.R.V.I.S. (voiced by Paul Bettany) operating system from the Iron Man Films would turn into the villain.

Marvel vets RDJ, Chris Evans Chris Hemsworth Scarlett Johansson Samuel L. Jackson Jeremy Renner Mark Ruffalo, Clark Gregg and Cobie Smulders are all expected back Two time Iron Man co-star Don Cheadle is involved this time out according to USA Today. Bettany will appear on screen as The Vision an android created by Ultron as a weapon to be used against the Avengers. Vision can fire beams of radiation and turn invisible--the character ultimately turned the tables on Ultron and became an Avengers member himself.

Thomas Kretschmann has landed the role of 2nd bad guy Baron von Strucker. In the comics, the seemingly immortal Strucker is one of the leaders of Hydra, and an enemy of both S.H.I.E.L.D and The Avengers He seemingly beat out rumored candidates Marton Csokas and Dougray Scott who were being considered for the BvS role. The character will have Wanda Maximoff, a.k.a. Scarlet Witch (Elizabeth Olsen) and her twin brother Quicksilver (Aaron Taylor-Johnson) apparently working for him in the sequel (American Horror Story favorite Evan Peters plays a different incarnation of the speedy superhero in Bryan Singer's "X-Men: Days of Future Past"--now in post-production--that film hits screens May 23rd 2014.). Korean actress  Soo-hyun Kim will play a bad gal role.

Radar Online has an unidentified source that claims that RDJ is campaigning to get his pals Mel Gibson and Jodie Foster a role in the movie.

Some non principal filming is also taking place in South Africa Production on the 'Avengers' sequel is slated to begin in earnest next month to meet a release date of May 1, 2015.
