Outside of Tom Hiddleston’s villainous Loki returning in The Avengers after his introduction in Thor as the primary villain, Marvel Studios has kept a sealed lid on any official information regarding the other baddies that Earth’s Mightiest Heroes will have to battle against. In fact, we haven’t really seen too much of the principal cast leaked online either.

Along with the button at the end of Captain America: The First Avenger, eager fans were given their first real look at The Avengers roster during Comic-Con when Marvel released character posters for the team, that could fit together, forming a larger image. Today, we have a few more pieces of artwork, depicting the team posing together, fighting together and a little more.

The recent onslaught of set photos and videos of the final weeks of shooting The Avengers in Cleveland may at first, appear to offer plenty, but in reality we only got a good look at two heroes we already knew about with some potential spoilers regarding Loki’s “army” and the vehicles they use. All of the months of production before it gave rise to no spoilers at all so there’s still plenty of surprises left to come… that is, if the leaked images from the cancelled Avengers movie tie-in game didn’t spoil it already. Then again, anyone who’s been paying attention knows who the other villains of Joss Whedon’s film will be anyway.

Today, check out this new video highlighting The Avengers roster and the cast of actors playing them – then follow that with a look at some promo artwork of the Avengers standing together.

The four new images come from Spider Media and all take the form of conceptual and promotional art, but they do provide another detailed look at The Avengers team together in full costume – Click for super high res versions:

When you step back and really think about these images, these actors and the characters they’re playing on the silver screen, it’s hard to fathom that it’s really happening. Marvel has successfully brought to life Iron Man, Captain America and Thor and they’re actually going to join forces to fight the biggest threat we’ve seen in the movies to date. Enjoy it, fans. It’s been a long time coming.

The Avengers stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Scarlett Johansson, Jeremy Renner, Samuel L. Jackson, Cobie Smulders, Clark Gregg, Tom Hiddleston and Stellan Skarsgard. It is of course written and directed by Joss Whedon, opening in theaters on May 4, 2012.
