Unfortunately for fans of the Marvel Cinematic Universe there are a limited number of badges available for San Diego Comic-Con 2014, and an even more limited number of chairs in Hall H. Only a lucky few got to see the first trailer/sizzle reel for next summer’s blockbuster The Avengers: Age of Ultron, which debuted alongside the news that Guardians of the Galaxy 2 has been confirmed for release in July 2017.

Fortunately for our readers, Screen Rant was among those lucky few in Hall H, and we have a detailed breakdown of what happened in the Avengers: Age of Ultron trailer. The teaser revealed the first movie footage of Ultron, who first appears as a very old, very battered version of Iron Man’s suit that moves in a zombie-like fashion. After a montage of ominous scenes, Tony Stark is left standing in what looks like a barren wasteland, with the rest of the Avengers laid out before him – apparently dead – and Captain America’s shield shown shattered upon the ground.

For those who have trouble closing their eyes and imagining what the above images might have looked like, we have good news. Marvel brought some of the props seen in the trailer to Comic-Con, including Ultron Mk. 1 and Captain America’s broken shield, and today released images of both. Now that’s one creepy robot.

There are a few theories bouncing around regarding what the final scene of the trailer might mean. An exclusive set of posters for The Avengers: Age of Ultron has been released over the course of Comic-Con, showing the entire team (including Vision) engaged in what looks like a hopeless battle against Ultron’s army of robots. Two of them are shown gripping Captain America’s shield as he attempts to fight them off, so it’s possible that what was shown in the trailer was the aftermath of this battle.

The other possibility, of course, is that the entire thing is a vision conjured up by Scarlet Witch, using her powers to get inside’s Tony Stark’s head. The trailer also showed Hulk brawling with Iron Man (in his Hulkbuster armor), which could also be the result of Scarlet Witch working her influence on the big green guy.

In addition to the trailer reveal and props, most of the main cast of The Avengers: Age of Ultron were in attendance at Comic-Con this year. To see what they look like out of costume – and standing next to some of the other cool movie props that were showcased – check out our massive gallery of photos from SDCC 2014.
