WATCH: Final Trailer for Avengers: Age of Ultron

As ensemble casts go, Avengers surely has to offer one of the greatest in recent memory. 

We're counting down the days until Robert Downey Jr, Chris Hemsworth, Chris Evans, Mark Ruffalo and Scarlett Johansson (to name but a few), reunite on the big screen but to keep you ticking over until then, feast your eyes on the final trailer.

The sequel to 2012 smash hit Avengers, Avengers Age of Ultron sees Tony Stark attempt to jumpstart a dormant peacekeeping program. Of course, things go wrong - and it is up to the Avengers to stop the villainous Ultron.
