I happened across this earlier today on a TGDaily article (which is why I should give them the credit to be fair), but wanted to share this with everyone since this is going to be one of the most anticipated movies of 2012 - not to mention I'm super excited about it being a huge fan of the recent series of Marvel comic movies.
Norton (yes, the Symantec owned computer software security company) had this behind the scenes sneak-preview of what's what and happening in The Avengers - slated for a worldwide release on April 11th 2012 and a May 4th release in the US.
