It's Iron Man versus Hulk, and it looks amazing.

First-Look 'Avengers: Age Of Ultron' Footage Brings Down The House At Comic-Con

After dancing out onto the stage at Hall H in San Diego Comic-Con, the cast of "Avengers: Age of Ultron" presented the first footage from the upcoming super sequel.

Scarlett Johansson couldn't make it, but she introduced the first look via video.

We open on Avengers Tower, a post-mission party. The game is to pick up Thor's hammer. Tony goes first and adds an Iron Man hand to help. Rhodey can't even help. Cap tries and nearly moves it, making Thor look nervous.

Ultron, looking only partially complete, stumbles onto the scene. He's clearly made from Iron Man parts. He talks about the problem with the Avengers and why they are unworthy, before sending in drone suits to attack them.

The feeling of the footage is truly global. We were transported around the globe. There's so much to see, all passing by quickly. Loki's staff makes a cameo, along with Andy Serkis in human form.

"This is the end," says Tony. "The end of a path I started us on."

We then see a fight between Hulk and Tony in his Hulkbuster armor. It looks like a hell of a battle.

The footage ends with Cap's shield broken. Tony wakes up to see the Avengers scattered on a rock that looks like it's floating in space.
