We've all seen the Avengers: Age of Ultron trailer, right? RIGHT?!?! Well, if you haven't, shame on you! Hand over your Geek Card, please! Just kidding... sort of. But, seriously, check the teaser trailer out.

However, it's perfectly fine if you see the below clip first. Actually, it sets up the context of the teaser trailer a little bit more. Check out Iron Man, War Machine, and Captain America try to prove themselves worthy of lifting Thor's hammer... and then... well, give it a watch.
