New Promo Character Posters and Image of Loki from THE AVENGERS

We’re about to get a brand new look at Joss Whedon’s The Avengers this Sunday during the Super Bowl (watch a teaser for the spot here), but today a couple of promotional banners hit the web. They’re reminiscent of the numerous character banners we’ve seen previously, but we get another look at the elusive Hulk. As the fllm’s release date looms closer, we should be seeing more and more of the Mark Ruffalo-infused green alter ego as the visual effects work progresses. The banners also give us a small look at Cobie Smulders’ Agent Maria Hill. In addition, a new image of Tom Hiddleston looking fairly maniacal as Loki has hit the web, so that’s included after the jump as well.

Hit the jump to check out the banners. The film also stars Robert Downey Jr., Chris Hemsworth, Chris Evans, Samuel L. Jackson, Scarlett Johansson, and Jeremy Renner. The Avengers opens in IMAX 3D on May 4th.
