Avengers: Age of Ultron

If you hadn't heard, the new Avengers: Age of Ultron teaser trailer came out yesterday. Originally, it was supposed to come out on Tuesday next week but when a crappy version got leaked on the internet last night, this is how Marvel responded (the bottom tweet came first):

(Hydra is was the bad guys in Captain America: The Winter Soldier.)
But this just shows how the internet has changed the entertainment industry. Marvel knows that once a leaked version is out there, people will hunt it down until they have seen it. So rather than have fans watch an illegally downloaded version, Marvel just decided to release it.
This trailer is just the teaser trailer, which often doesn't reveal much of the storyline and is mainly action scenes, but this one is over two minutes long. This is giving me very high expectations for the real trailer.
