Today Marvel kicks off their big Promo run for Avengers: Age of Ultron with our first look at the Final Movie Poster. While it appears they have fixed the lighting issues from the first Avengers poster, they have outdone themselves this time by spoiling what could’ve been a great surprise cameo. Hit the jump for the cameo and more potential spoilers.

Thanks to StichKingdom, we have an awesome Hi-res poster that allows us to check out all of the tiny credits text. Most notably, as I mentioned earlier, is the inclusion of Anthony Mackie, who played Sam Wilson/Falcon in Captain America: The Winter Soldier. Additionally, Hayley Atwell (who was confirmed a while ago) is included as well as Idris Elba; who accidentally revealed he would be returning a few months months back.

The biggest surprise though, is the appearance of Danny Elfman, who is credited with ‘Additional Music By’. Dave Gonzales over at Latino Review, as well as a few others have speculated that this could possibly be our first hint at some sort of Spider-Man inclusion in Age of Ultron seeing as Danny Elfman was responsible for the 2002 Spider-Man Theme. I’m of the opinion that we’ll only see him in a post-credits scene and even that is a bit of a stretch. Marvel would be insane not to attach a Spider-Man post-credits scene to Ant-Man and use that as a promotional vehicle to help give Ant-Man a little extra boost.
