As Ultron would say, "I'm gonna show you something beautiful!"
Marvel Studios' conceptual artist, Phil Saunders (Iron Man 3, The Avengers), has uploaded four more of his designs of the villainous robot (head design by Ryan Meinerding) -- with brief descriptions -- that were not used in the film.
Below, check out the concept art and captions.
"One of the final round of designs before the direction was changed and we went back to the drawing board."
"Part of the third round of designs, after we were directed to make the design more clearly mechanical. A little too Terminator for my taste."
"A design based around Ryan Meinerding's more art deco version. Really loved the differential joint he used for the shoulders."
"Another version of the more organic design. Still my favorite of the versions I produced. But I'm a sucker for speed forms!"
The epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to the Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.
