Ultron gets his AVENGERS: AGE OF ULTRON Character Poster Iron Man is sooo 2014. The robotic entity Ultron is stronger, faster, shinier, and -of course- crazier than Tony Stark’s alter ego. Take a look at the titular villain -voiced by James Spader- of AVENGERS: AGE OF ULTRON in his (its?) somber character poster. AVENGERS: AGE OF ULTRON will be released in theaters on May 1st, 2015. When Tony Stark tries to jump-start 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 a global adventure.
