Marvel has released the official synopsis for the film:
Marvel Studios presents “Avengers: Age of Ultron,” 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.
Marvel’s “Avengers: Age of Ultron” stars Robert Downey Jr., who returns as Iron Man, along with Chris Evans as Captain America, Chris Hemsworth as Thor and Mark Ruffalo as The Hulk. Together with Scarlett Johansson as Black Widow and Jeremy Renner as Hawkeye, and with the additional support of Samuel L. Jackson as Nick Fury and Cobie Smulders as Agent Maria Hill, the team must reassemble to defeat James Spader as Ultron, a terrifying technological villain hell-bent on human extinction. Along the way, they confront two mysterious and powerful newcomers, Wanda Maximoff, played by Elizabeth Olsen, and Pietro Maximoff, played by Aaron Taylor-Johnson, and meet an old friend in a new form when Paul Bettany becomes Vision. Written and directed by Joss Whedon and produced by Kevin Feige, Marvel’s “Avengers: Age of Ultron” is based on the ever-popular Marvel comic book series “The Avengers,” first published in 1963. Get set for an action-packed thrill ride when The Avengers return in Marvel’s “Avengers: Age of Ultron” on May 1, 2015.
Some have noted that Elizabeth Olsen’s and Taylor-Johnson’s characters are referred to be their actual names in the synopsis, rather than a superhero moniker, like the rest of the Avengers. Well, it’s simple, really. They were introduced at the end of Captain America: The Winter Soldier as potential nemesis for the Avengers, so it’s unlikely they’ll be conferred lofty, ego-inflating superhero names right at the start.
Other things we know about the film: Thanos, the supervillain who makes a brief cameo in Guardians of the Galaxy, will not be appearing in Avengers: Age of Ultron. No worries. Since he’s primed to be the next big antagonist of Marvel’s Phase Three, we suspect we’ll be seeing him a lot more. Also, will the Black Panther, who is not mentioned in the official plot details at all, be appearing in the film? We’ll just have to wait and find out.
Avengers: Age of Ultron opens in Singapore on 30 April 2015.
