It seems that Marvel's policy of not videotaping the Avengers Age of Ultron Comic Con trailer was for naught as the Avengers Age of Ultron Comic Con trailer leaked online!

It has been reported that just like the Batman vs Superman teaser, the Avengers Age of Ultron Comic Con trailer leaked online as well. While we haven't seen a copy floating around, we will post it here so keep on coming back to this page to see the Avengers Age of Ultron comic con trailer.

This is a description of the Avengers Age of Ultron trailer as noted by Comicbook.com:

"Age Of Ultron trailer opens with a party scene at Avengers tower. The Avengers are trying to lift Thor's hammer Mjolnir. Tony Stark is the first to try, but he can't do it, even using his Iron Man hand. Rhodey tries to help, but he fails as well. Hawkeye and Bruce Banner both try and meet the same failure. Steve Rogers seems to move it just a little bit, but not much."

"Thor says, 'You're all not worthy.'"

"A noise catches their attention. Then, there's a first look at Ultron, who says, 'There's only one path to peace. Your extinction.'"

"There's a montage of various scenes, different places, explosions. Bruce Banner is in the woods. Tanks are fighting in the snow."

"Tony Stark says, 'It's the end. The end of the path I started us on.'"

"Black Widow says, 'Nothing lasts forever.'"

"Tony Stark is in the Hulkbuster armor, which he is using to fight the Hulk."

"A fully-formed Ultron says, "Look no string on me.""

"Tony Stark is in what looks like a wasteland with all the Avengers lying, battered and beaten before him, even Captain America's shield is broken."

The final shots of the Avengers Age of Ultron Comic Con trailer show the Avengers defeated and seemingly dead lying on what many are speculating is Thanos' lair.

It's all very epic. It's unfortunately going to be a while before Marvel makes the trailer available to the public, though. "The Avengers: Age of Ultron" hits theaters on May 1, 2015.

In addition to showing the trailer, the "Avengers" panel revealed a rather big tease: Josh Brolin, who plays the character of Thanos, wearing The Infinity Gauntlet. Fans can see his version of Thanos for the first time in "Guardians of the Galaxy," which is out in theaters Aug. 1, 2014.
