Captain America: The First Avenger is out in one day – zero if you’re at Comic-Con – and the reviews so far have been … well, pretty good. The general consensus seems to be: Imperfect, but old-fashioned fun.

Once Cap hits, all eyes will be on May 2012 and the release of Joss Whedon’s The Avengers. As such, Marvel launched the Avengers website yesterday, featuring the first official teaser poster and some pictures of the new S.H.I.E.L.D. uniforms from Comic-Con. Plus: We’ve got a closer look at the new Cap, Iron Man, and Thor costumes via their action figures.

First, check out The Avengers teaser poster from the newly launched website (click to enlarge):

It’s not much, but it’s simple and slick. Who knew one word – “assemble” – could say so much?

From Marvel Dot Com, we’ve got our closest, clearest look at Captain America in The Avengers (click to enlarge):

Basically, it looks like an amalgamation of his costume from The First Avenger and The Ultimates. No surprises here. Still, it’s a bit strange that this costume only looks slightly more futuristic than his costume from nearly 70 years prior.

Also from Marvel, check out the mock-up of the interior of the S.H.I.E.L.D. Helicarrier and the agents’ brand-new uniforms:

This is the first time in these movies that S.H.I.E.L.D. agents have worn something semi-futuristic, a la the comic books. In previous Marvel films, they’ve just looked like your typical government agents. Suits, shades, et cetera. No longer.

Now check out the new Avengers action figures and costumes via Comic Book Movie (click to enlarge):

These things look pretty much identical to the leaked artwork costumes, though slightly different from the ones in the brief footage that popped up on the internet recently, at least in Iron Man and Thor’s case. Though it’s more than possible that they’ll wear both costumes in the film.

Also, does Iron Man’s costume – and specifically, the color scheme of his costume (yellow, gray, blue arc reactor) – resemble that of Ultimate Iron Man?

Just a little bit?

Lastly, Captain America‘s screenwriters recently talked to io9 about the star-spangled Avenger, amongst other things. Near the end of the interview, Stephen McFeely let slip that there will almost definitely be some conflict between Cap and Iron Man in The Avengers:

It’s safe to say that in The Avengers [Iron Man and Captain America] certainly have friction.

Stay tuned for more SDCC coverage and Avengers news in the next few days.

The Avengers hits theaters May 4th, 2012.
