The second trailer for 'Avengers: Age of Ultron' has just be released and it looks more epic than ever, but also a little dark too. This trailer shows that it might not be the smooth easy ride to saving the world for our favourite Marvel superheroes that was promised in the first trailer. The Hulk looks pretty unstable, Thor seems to be having trouble with the electricity that he is usually capable of summoning himself and Tony Stark seems to be having a few issues of his own.
It still promises to be a lot of fun however and theres a couple of characters spotted in this trailer that we don't know much about yet which is very exciting. Take a look for yourself.
