Find Out Who's The Boss In New Avengers: Age Of Ultron Trailer

It's usually pretty easy to guess who the boss is in any organisation: look for the one with all the money who's telling everyone what to do.

So we wouldn't blame you for having assumed that Tony Stark (aka Iron Man, aka Robert Downey Jr.) was really in charge of The Avengers - although it's a position he denies holding in the latest trailer for Avengers: Age Of Ulton.

When addressed as "boss" by an assistant, he points at Captain America (Chris Evans) and says in an offhand manner: "Actually he's the boss."

He then explains: "I just pay for everything and design everything and make everyone look cooler."

The action-packed promo then runs through Earth's Mightiest Heroes one-by-one, showing a brief glimpse of each in action.

And it finishes up with new arrivals Scarlet Witch and Quicksilver - played by Elizabeth Olsen and Aaron Taylor-Johnson.

The movie opens in the UK on 24 April.
