Set to hit theaters on May 1, “Avengers: Age of Ultron” (watch the trailer here) has released new posters starring Scarlett Johansson as Black Widow and other stars. The official synopsis for the film is described by Marvel as follows: “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.”
