Everyone is dying to see the first footage of "Avengers: Age of Ultron." At Comic-Con, that footage was shown, but all the Comic-Con trailers are made to be hidden behind closed doors and not released.

Well, Yahoo! has just seen the footage as well, and they describe just what happens in those fateful minutes. Apparently, not only do we get a glimpse at new costumes for the Avengers, as well as new Avengers Quicksilver (played by Aaron Taylor-Johnson) and Scarlet Witch (played by Elizabeth Olsen,) but we get our first glimpse at new "Avengers" villain Ultron, a killer robot with plans for world domination.

Ultron will be voiced by James Spader in the film.

Now, one brave soul who saw the Comic-Con trailer has done a great service to all those who can't. ComicBook.com reports that a Youtube user named Jahaziel Brito has created the first "Avengers: Age of Ultron" trailer, only without the actual footage, he has sketched the trailer's images from memory.

The audio, meanwhile, is inserted in from a bootleg that managed to capture the trailer's dialogue at Comic-Con.

While it's not much, it's by far the best thing we have so far, and it gives us a little glimpse at what "Avengers: Age of Ultron" holds. And it looks absolutely terrific.

Hopefully, Brito's video will spurn Marvel into releasing the footage in earnest, because now we've basically seen it all anyway.

However, there's still one thing not yet shown in that first Comic-Con trailer: Erik Selvig's bare butt.

According to Bleeding Cool, the character played by Stellan Skarsgard will be returning in the "Avengers" sequel, and he will be performing a nude scene- something the actor did previously in "Thor: The Dark World."

Check back soon for updates on the "Avengers: Age of Ultron" trailer- and see the storyboard video below.
