Marvel have released the first official synopsis for Avengers: Age of Ultron, and you can read it here:

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.

So, what does this tell us about the movie? Well, the fact that Tony Stark inadvertently creates Ultron while trying to “jumpstart a dormant peacekeeping program” is very interesting, and not something which happened in the comics. There have been rumours that at least part of Ant-Man will feature S.H.I.E.L.D., so will this movie tie-into that by having Hank Pym still be the original creator of Ultron? (albeit inadvertently).

The mention that the fate of the planet is in jeopardy is also very telling when it comes to just how much of a threat Ultron will be in the movie, while Marvel seemingly drop a very revealing hint that The Vision is indeed an upgraded J.A.R.V.I.S. as many fans have been suspected from the moment he was cast.

Regardless, Avengers: Age of Ultron looks set to be one of THE most exciting movies of 2015 and we’ll be sure to keep you updated as a trailer can’t be too far away now. Of course, there are plenty of great releases to look forward to still in 2014 and you can find the 20 we believe to be the most essential right here.
