Seeing as this is the internet, and I'm talking about the next "Avengers" movie, there's a pretty good chance you already know that the trailer for it has leaked. As a result, Marvel have gone ahead and posted it officially to their YouTube account in hi-def. So, in case the bootleg copy you watched an hour ago was too grainy, or in case you didn't know yet, you can watch it below. It doesn't really reveal very much that we didn't know (or at least suspect) already, but it does look really cool. See you all in the theaters next year!
