A new wave of character posters have been arriving this week for Avengers: Age of Ultron, with the stars themselves releasing the one-sheets through their official Twitter accounts. Apparently Samuel L. Jackson has become the ambassador for his Twitter-less cast mates, debuting posters for his own character Nick Fury, along with Scarlett Johansson's Black Widow and Chris Hemsworth's Thor earlier today. It's clear that all of these one-sheets take place at the same battle, but since they all have slightly different backgrounds, perhaps they will all form one gigantic poster, similar to the one Marvel debuted at Comic-Con last summer.

In Avengers: Age of Ultron, Tony Stark attempts to jumpstart a dormant peacekeeping program. Things soon 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.

As of now, Chris Evans' Captain America and Jeremy Renner's Hawkeye are the only Avengers left without their own posters thus far, but other characters such as new additions Quicksilver (Aaron Taylor-Johnson), Scarlet Witch (Elizabeth Olsen) and Ultron may get their own one-sheets as well. This poster roll-out could also be the perfect opportunity to give fans the first real look at Vision, played by Paul Bettany, but we'll have to wait and see. In the meantime, take a look at Thor's poster below, and stay tuned for more on Avengers: Age of Ultron, arriving in theaters May 1.
