The Avengers official trailer is now available. Its suppose to be an exclusive on iTunes but I found a Youtube version already up. I hope it does not get pulled because of exclusive rights or some BS like that.But if it does here is the iTunes link . Also you can go the official Avengers site at:http://avengers.marvel.com which will give yo a link back to iTunes orrrrrrr you can go to this page at Marvel that has a story synopsis that I copied and pasted below and also has the trailer.
