Why is this a big deal? Well it's only the sequel to the third highest grossing movie OF ALL TIME (2012's The Avengers) and another cresendo for the increasingly awesome superhero team. For some people though its a chance to see a film writtten and directed by one of the greatest minds working in the business - that's Joss Whedon. And remarkably enough, its still only the fourth feature from the man called Joss.In the event that you aren't fully aware of how awesome this all is, the final trailer for Age of Ultron is set to debut on ABC during show American Crime on the 5th of March. That's good news for those of you who are watching in the US (boo!) but for everyone else, the promo is likely to be online very soon after that.In Age of Ultron the team including Iron Man, Thor, Hulk, Captain America, Hawkeye and Black Widow are having good superhero times until a new villain shows up in the form of Ultron - a robotic enemy created by none other than Tony Stark. This is going to get heavy.
