There’s Marvel with the best official response I can remember for a big leak. This afternoon, the Avengers: Age of Ultron trailer leaked, only hours after being announced for an official debut next week.

So Marvel did the only thing it could do, and dropped the official release. Below, you can see the Age of Ultron trailer in official quality, which is much better than that (admittedly good) bootleg.

Most of what is in the trailer is what we saw at Comic Con this past summer, though it is missing a few bits and (I think) adds others. It’s a very serious trailer, but we get to see quite a lot of the main players, including the title villain, Ultron. And yet it doesn’t really tell us anything at all. In fact there’s a good amount of Ultron, as well as some Quicksilver and Scarlet Witch, and that Hulkbuster armor everyone is psyched about. (Personally, it’s Ultron I want to see, but I can tell why the Hulkbuster thing is a big deal.)

This trailer is big and ominous and destructive, but it’s the little shots that catch my eye. What’s up with the ballerinas — is that Quicksilver playing piano? Is that in fact a human Andy Serkis a few seconds earlier? Love the shots of a very troubled Banner, and the isolated Black Widow. (And a shot that was suggestive of a new character in the low-res bootleg is now obviously just a person diving for cover when seen in HD.)

Avengers: Age of Ultron opens on May 1, 2015.
